I understand that this is the safest way to change or reset mysql root password. I'm doing it because 8 times out of 10 the installation program won't prompt me for a root password.
So I run commands:
sudo /etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables &
sudo mysql -u root
use mysql;
Then, depending on your version of mysql or maria you're using you type:
update user set password=PASSWORD("mynewpassword") where User='root';
or
ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
In my case I typed the first one. Then I refresh privileges by:
flush privileges; and then I exit out of mysql by typing: quit.
At this point everything went well. Then I restart mysql server by:
sudo /etc/init.d/mysql start
I get "OK" from the terminal. However, when I attempt to log in as root
I get pleasant error message saying:
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
I'm 100% confident that I'm typing correct password. Why is this happening ?
Problem resolved by backing up all important data and reinstalling the operating system. As turned out I had some broken packages that affected how mysql authentication worked. Standard steps to fix broken packages was no use so I wiped out HDD and started over.
MySQL was installed without any hiccups and was even prompted for a root password to be set. Now MySQL authentication works like a charm.
Try this out :- It Works for me..!!
Stop the MySQL server process.
service mysql stop
Start the MySQL (mysqld) server/daemon process with the –skip-grant-tables option so that it will not prompt for password.
mysqld_safe --skip-grant-tables > /dev/null 2>&1 &
Connect to mysql server as the root user. And Setup new mysql root account password.
mysql -u root -e "use mysql; update user set password=PASSWORD('NEW-PASSWORD') where User='root'; flush privileges;"
Exit and restart the MySQL server.
service mysql restart
Note: You may need to wait after mysqld_safe command, before you can run subsequent mysql command.
Now run :- mysql -u root -p
I have been following a manual to install a software suite on Ubuntu. I have no knowledge of MySQL at all. I have done the following installations on my Ubuntu.
sudo apt-get update
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-client-5.5
sudo apt-get install mysql-common
sudo apt-get install glade
sudo apt-get install ntp
Then I do
cd ~/Desktop/iPDC-v1.3.1/DBServer-1.1
mysql -uroot -proot <"Db.sql"
I ended up with the following error message.
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
How may I fix it and continue?
Note: For MySQL 5.7+, please see the answer from Lahiru to this question. That contains more current information.
For MySQL < 5.7:
The default root password is blank (i.e., an empty string), not root. So you can just log in as:
mysql -u root
You should obviously change your root password after installation:
mysqladmin -u root password [newpassword]
In most cases you should also set up individual user accounts before working extensively with the database as well.
I was recently faced with the same problem, but in my case, I remember my password quite alright, but it kept on giving me the same error. I tried so many solutions, but still none helped. Then I tried this:
mysql -u root -p
After which it asks you for a password like this
Enter password:
And then I typed in the password I used. That's all.
I was able to solve this problem by executing this statement
sudo dpkg-reconfigure mysql-server-5.5
Which will change the root password.
You have to reset the password! Steps for Mac OS X (tested and working) and Ubuntu:
Stop MySQL using
sudo service mysql stop
or
sudo /usr/local/mysql/support-files/mysql.server stop
Start it in safe mode:
sudo mysqld_safe --skip-grant-tables --skip-networking
(the above line is the whole command)
This will be an ongoing command until the process is finished, so open another shell/terminal window, log in without a password:
mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
As per #IberoMedia's comment, for newer versions of MySQL, the field is called authentication_string:
mysql> UPDATE mysql.user SET authentication_string =PASSWORD('password') WHERE User='root';
Start MySQL using:
sudo service mysql start
or
sudo /usr/local/mysql/support-files/mysql.server start
Your new password is 'password'.
Note: for version of MySQL > 5.7 try this:
update mysql.user set authentication_string='password' where user='root';
It happens when your password is missing.
Steps to change the password when you have forgotten it:
Stop MySQL Server (on Linux):
sudo systemctl stop mysql
Start the database without loading the grant tables or enabling networking:
sudo mysqld_safe --skip-grant-tables --skip-networking &
The ampersand at the end of this command will make this process run in the background, so you can continue to use your terminal and run mysql -u root (as root). It will not ask for a password.
If you get error like as below:
2018-02-12T08:57:39.826071Z mysqld_safe Directory '/var/run/mysqld' for UNIX
socket file don't exists.
mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)
[1]+ Exit 1
Make MySQL service directory.
sudo mkdir /var/run/mysqld
Give MySQL user permission to write to the service directory.
sudo chown mysql: /var/run/mysqld
Run the same command in step 2 to run MySQL in background.
Run mysql -u root. You will get the MySQL console without entering a password.
Run these commands
FLUSH PRIVILEGES;
For MySQL 5.7.6 and newer
ALTER USER 'root'#'localhost' IDENTIFIED BY 'new_password';
For MySQL 5.7.5 and older
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('new_password');
If the ALTER USER command doesn't work use:
UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';
Now exit
To stop the instance started manually:
sudo kill `cat /var/run/mysqld/mysqld.pid`
Restart MySQL
sudo systemctl start mysql
At the initial start up of the server the following happens, given that the data directory of the server is empty:
The server is initialized.
SSL certificate and key files are generated in the data directory.
The validate_password plugin is installed and enabled.
The superuser account 'root'#'localhost' is created. The password for the superuser is set and stored in the error log file.
To reveal it, use the following command:
shell> sudo grep 'temporary password' /var/log/mysqld.log
Change the root password as soon as possible by logging in with the generated temporary password and set a custom password for the superuser account:
shell> mysql -u root -p
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass5!';
If the problem still exists, try to force changing the password:
/etc/init.d/mysql stop
mysqld_safe --skip-grant-tables &
mysql -u root
Set up a new MySQL root user password:
use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;
Stop the MySQL server:
/etc/init.d/mysql stop
Start the MySQL server and test it:
mysql -u root -p
If none of the other answers work for you, and you received this error:
mysqld_safe Logging to '/var/log/mysql/error.log'.
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
[1]+ Exit 1 sudo mysqld_safe --skip-grant-tables
Follow the below commands step by step until you reset your password:
# Stop your server first
sudo service mysql stop
# Make the MySQL service directory.
sudo mkdir /var/run/mysqld
# Give MySQL permission to work with the created directory
sudo chown mysql: /var/run/mysqld
# Start MySQL, without permission and network checking
sudo mysqld_safe --skip-grant-tables --skip-networking &
# Log in to your server without any password.
mysql -u root mysql
# Update the password for the root user:
UPDATE mysql.user SET authentication_string=PASSWORD('YourNewPasswordBuddy'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';
# If you omit (AND Host='localhost') section, it updates
# the root password regardless of its host
FLUSH PRIVILEGES;
EXIT;
# Kill the mysqld_safe process
sudo service mysql restart
# Now you can use your new password to log in to your server
mysql -u root -p
# Take note for remote access. You should create a remote
# user and then grant all privileges to that remote user
I came across this very annoying problem and found many answers that did not work. The best solution I came across was to completely uninstall MySQL and reinstall it. On reinstall you set a root password and this fixed the problem.
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.5 mysql-client-core-5.5
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get autoremove
sudo apt-get autoclean
I found this code elsewhere, so I don't take any credit for it. But it works. To install MySQL after uninstalling it, I think DigitalOcean has a good tutorial on it. Checkout my gist for this.
How to install MySQL on Ubuntu (which works)
I am using Ubuntu 16.04 (Xenial Xerus) and installed MySQL 5.7.
I had the same issue
Login denied for root user.
I tried the below steps:
dpkg --get-selections | grep mysql (to get the version of MySQL).
dpkg-reconfigure mysql-server-5.7
mysql -u root -p
Without -p that doesn't prompt you to ask password. Once you are in, you can create a user with a password by following steps:
CREATE USER 'your_new_username'#'your-hostname' IDENTIFIED BY 'your-password';
GRANT ALL PRIVILEGES ON *.* to 'your_new_username'#'your-hostname' WITH GRANT OPTION;
Exit from the root and log in from the <name> you gave above.
mysql -u <your_new_username> -p
For some reason still just typing MySQL does not work. At all. I suggest to make it a habit to use mysql -u <name> -p.
In the terminal, just enter:
mysql -u root -p
Then it will ask the password from you.
I installed MySQL as root user ($SUDO) and got this same issue
Here is how I fixed it:
sudo cat /etc/mysql/debian.cnf
This will show details as:
# Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock
Above we can see the password. But we are just going to use(GUx0RblkD3sPhHL5) that in the prompt.
`mysql -u debian-sys-maint -p
Enter password: `
Now provide the password (GUx0RblkD3sPhHL5).
Now exit from MySQL and log in again as:
`mysql -u root -p
Enter password: `
Now provide the new password. That's all. We have a new password for further uses.
It worked for me.
For those for whom the current answers didn't work can try this (tested on macOS):
mysql -h localhost -u root -p --protocol=TCP
After this, a password will be asked from you and you should use your OS user password. Then when you get into MySQL you can run:
select Host, User from mysql.user;
And you should see:
MySQL [(none)]> select Host, User from mysql.user;
+-----------+------------------+
| Host | User |
+-----------+------------------+
| localhost | mysql.infoschema |
| localhost | mysql.session |
| localhost | mysql.sys |
| localhost | root |
+-----------+------------------+
And from here you can change the configurations and edit the password or modify the grants.
Please read the official documentation: MySQL: How to Reset the Root Password
If you have access to a terminal:
MySQL 5.7.6 and later:
mysql
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
MySQL 5.7.5 and earlier:
mysql
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
I am using mysql-5.7.12-osx10.11-x86_64.dmg on Mac OS X.
The installation process automatically sets up a temporary password for the root user. You should save the password. The password can not be recovered.
Follow the instructions:
Go to cd /usr/local/mysql/bin/
Enter the temporary password (which would look something like, "tsO07JF1=>3")
You should get the mysql> prompt.
Run, SET PASSWORD FOR 'root'#'localhost' = PASSWORD('{YOUR_PASSWORD}'); If you wish to set your password: "root" then the command would be, SET PASSWORD FOR 'root'#'localhost' = PASSWORD('root');
Run ALTER USER 'root'#'localhost' PASSWORD EXPIRE NEVER;
Run exit
Run ./mysql -u root -p
Type your password. In my case I would type, "root" (without quote)
That's all.
For convenience, you should add "/usr/local/mysql/bin" to your PATH environment variable.
Now from anywhere you can type ./mysql -u root -p and then type the password and you will get the mysql> prompt.
The answer may sound silly, but after wasting hours of time, this is how I got it to work:
mysql -u root -p
I got the error message
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
Even though I was typing the correct password (the temporary password you get when you first install MySQL).
I got it right when I typed in the password when the password prompt was blinking.
If you have MySQL as part of a Docker image (say on port 6606) and an Ubuntu install (on port 3306) specifying the port is not enough:
mysql -u root -p -P 6606
will throw:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
as it's trying to connect to localhost by default, specifying your local IP address fixes the issue:
mysql -u root -p -P 6606 -h 127.0.0.1

Answer for Ubuntu 20.04 (Focal Fossa) (maybe other distributions as well).
After days of wandering around... and having none of those answers working for me, I did this and it worked!
Always in a Bash shell:
sudo systemctl disable mysql
In order to stop the daemon from starting on boot.
sudo apt purge mysql-server
and
sudo apt purge mysql-community-server*
There, it warns you you'll erase configuration files... so it's working! Because those are the ones making trouble!
sudo autoremove
To delete all the left behind packages.
Then (maybe it's optional, but I did it) reboot.
Also, I downloaded mysql-server-8.0 from the official MySQL webpage:
sudo apt install mysql-server
A signal that it's working is that when you enter the command above, the system asks you to enter the root password.
Finally:
mysql -u root -p
And the password you entered before.
If the problem still exists, try to force changing the password.
Stop MySQL Server (on Linux):
/etc/init.d/mysql stop
Stop MySQL Server (on Mac OS X):
mysql.server stop
Start the mysqld_safe daemon with --skip-grant-tables:
mysqld_safe --skip-grant-tables &
mysql -u root
Set up a new MySQL root user password:
use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;
Stop MySQL Server (on Linux):
/etc/init.d/mysql stop
Stop MySQL Server (on Mac OS X):
mysql.server stop
Start the MySQL server service and test to log in by root:
mysql -u root -p
I also came across the same problem. I did:
Open your cmd
Navigate to C:\Program Files\MySQL\MySQL Server 8.0\bin>
(where MySQL Server 8.0 may be different depending on the server you installed)
Then put the following command mysql -u root -p
It will prompt for the password... simply hit Enter, as sometimes the password you entered while installing is changed by to blank.
Now you can simply access the database.
This solution worked for me on the Windows platform.
By default, the password will be null, so you have to change the password by doing the below steps.
Connect to MySQL
root# mysql
Use mysql
mysql> update user set password=PASSWORD('root') where User='root';
Finally, reload the privileges:
mysql> flush privileges;
mysql> quit
Just one line and it solved my issue.
sudo dpkg-reconfigure mysql-server-5.5
In Ubuntu 16.04 (Xenial Xerus) and MySQL version 5.7.13, I was able to resolve the problem with the steps below:
Follow the instructions from section B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems
MySQL 5.7 reference manual
When I tried #sudo mysqld_safe --init-file=/home/me/mysql-init & it failed. The error was in /var/log/mysql/error.log:
2016-08-10T11:41:20.421946Z 0 [Note] Execution of init_file '/home/me/mysql/mysql-init' started.
2016-08-10T11:41:20.422070Z 0 [ERROR] /usr/sbin/mysqld: File '/home/me/mysql/mysql-init' not found (Errcode: 13 - Permission denied)
2016-08-10T11:41:20.422096Z 0 [ERROR] Aborting
The file permission of mysql-init was not the problem. We need to edit AppArmor permissions.
Edit by sudo vi /etc/apparmor.d/usr.sbin.mysqld
....
/var/log/mysql/ r,
/var/log/mysql/** rw,
# Allow user init file
/home/pranab/mysql/* r,
# Site-specific additions and overrides. See local/README for details.
#include <local/usr.sbin.mysqld>
}
Do sudo /etc/init.d/apparmor reload
Start mysqld_safe again. Try step 2 above. Check file /var/log/mysql/error.log. Make sure there is no error and the mysqld is successfully started.
Run mysql -u root -p
Enter password:
Enter the password that you specified in mysql-init. You should be able to log in as root now.
Shutdown mysqld_safe by sudo mysqladmin -u root -p shutdown
Start mysqld the normal way by sudo systemctl start mysql
While the top answer (with mysqladmin) worked on macOS v10.15 (Catalina), it did not work on Ubuntu. Then I tried many of the other options, including a safe start for MySQL, but none worked.
Here is one that does:
At least for the version I got 5.7.28-0ubuntu0.18.04.4 answers were lacking IDENTIFIED WITH mysql_native_password. 5.7.28 is the default on the current LTS and thus should be the default for most new new systems (till Ubuntu 20.04 (Focal Fossa) LTS comes out).
I found Can't set root password MySQL Server and now applied
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'your_pass_here';
which does work.
The error that I faced was:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO)
It was a problem with the port running on.
By default, MySQL is running on port 3306.
You can check that on by running
in a 32-bit system:
sudo /opt/lampp/manager-linux.run
in a 64-bit system:
sudo /opt/lampp/manager-linux-x64.run
and click on the Configure button.
In my case the port was running on 3307, and I used the command
mysql -u root -p -P 3307 -h 127.0.0.1
Copied from this link, I had the same problem and this solved the problem. After we add a password for the database, we need to add -p (password-based login), and then enter the password. Otherwise, it will return this error:
mysql -u root -p
Because your error message says "PASSWORD: YES" this means you are are using the wrong password. This happened to me also. Luckily I remembered my correct password, and was able to make the DB connection work.
In recent MySQL versions there isn't any password in the mysql.user table.
So you need to execute ALTER USER. Put this one line command into the file.
ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
And execute it as an init file (as the root or mysql user):
mysqld_safe --init-file=/home/me/mysql-init &
MySQL server need to be stopped to start mysqld_safe.
Also, there may be a problem with AppArmor permissions to load this init file. Read more in AppArmor and MySQL.
If you haven't set password yet, then run mysql -uroot. It works for me.
On Mac, if you have a problem in logging in with the first password you were given in installation, maybe you can just simply kill the MySQL process and then try.
So:
run the following command to find the PID of MySQL:
ps -aef | grep mysql | grep -v grep
kill the process:
kill -15 [process id]
Then you can log in with the initial password using this command:
mysql -uroot -p
Which asks you to enter your password. Just enter the initial password.
I cannot figure out my MySQL root password; how can I find this out? Is there any file where this password is stored?
I am following this link but I do not have directadmin directory in local.
thanks to #thusharaK I could reset the root password without knowing the old password.
On ubuntu I did the following:
sudo service mysql stop
sudo mysqld_safe --skip-grant-tables --skip-syslog --skip-networking
Then run mysql in a new terminal:
mysql -u root
And run the following queries to change the password:
UPDATE mysql.user SET authentication_string=PASSWORD('password') WHERE User='root';
FLUSH PRIVILEGES;
In MySQL 5.7, the password field in mysql.user table field was removed, now the field name is 'authentication_string'.
Quit the mysql safe mode and start mysql service by:
mysqladmin shutdown
sudo service mysql start
You can't view the hashed password; the only thing you can do is reset it!
Stop MySQL:
sudo service mysql stop
or
$ sudo /usr/local/mysql/support-files/mysql.server stop
Start it in safe mode:
$ sudo mysqld_safe --skip-grant-tables
(above line is the whole command)
This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:
$ mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
MySQL 5.7 and over:
mysql> use mysql;
mysql> update user set authentication_string=password('password') where user='root';
Exit the MySQL CLI:
mysql> exit
Restart MySQL in normal mode, first stopping the safe mode instance:
$ mysqladmin -u root -p shutdown # (when prompted, enter the new password just set)
$ sudo service mysql start
or
$ sudo /usr/local/mysql/support-files/mysql.server start
Your new password is 'password'.
MySQL 5.7 and above saves root in MySQL log file.
Please try this:
sudo grep 'temporary password' /var/log/mysqld.log
One thing that tripped me up on a new install of MySQL and wondering why I couldn't get the default password to work and why even the reset methods where not working.
Well turns out that on Ubuntu 18 the most recent version of MySQL server does not use password auth at all for the root user by default. So this means it doesn't matter what you set it to, it won't let you use it. It's expecting you to login from a privileged socket.
mysql -u root -p
This will not work, even if you are using the correct password.
Instead, you need to use:
sudo mysql
that will work with out any password.
then once you in you need type in
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'Password you want to use';
Then log out and now it will accept your password.
Follow these steps to reset password in Windows system
Stop Mysql service from task manager
Create a text file and paste the below statement
MySQL 5.7.5 and earlier:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('yournewpassword');
MySQL 5.7.6 and later:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'yournewpassword';
Save as mysql-init.txt and place it in 'C' drive.
Open command prompt and paste the following
C:\> mysqld --init-file=C:\\mysql-init.txt
You cannot find it. It is stored in a database, which you need the root password to access, and even if you did get access somehow, it is hashed with a one-way hash. You can reset it: How to Reset the Root Password
This worked for me:
On terminal type the following
$ sudo mysql -u root -p
Enter password://just press enter
mysql>
Unless the package manager requests you to type the root password during installation, the default root password is the empty string. To connect to freshly installed server, type:
shell> mysql -u root --password=
mysql>
To change the password, get back the unix shell and type:
shell> mysqladmin -u root --password= password root
The new password is 'root'. Now connect to the server:
shell> mysql -u root --password=
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO)
Oops, the password has changed. Use the new one, root:
shell> mysql -u root --password=root

As addition to the other answers, in a cpanel installation, the mysql root password is stored in a file named /root/.my.cnf. (and the cpanel service resets it back on change, so the other answers here won't help)
you can view mysql root password , well i have tried it on mysql 5.5 so do not know about other new version well work or not
nano ~/.my.cnf
The default password which worked for me after immediate installation of mysql server is : mysql
The procedure changes depending the version of MySql. Follow the procedure exactly as described for your version:
HINTS - Read before the instructions page for your version of MySql*
In step 5: Instead of run CMD, create a shortcut on your desktop calling CDM.exe. Then right-click on the shortcut and select "Execute as Administrator".
In step 6: Skip the first proposed version of the command and execute the second one, the one with the --defaults-file parameter
Once you execute the command, if everything is ok, the CMD window remains open and the command of step 6 continues executing. Simply close the window (click 'x'), and then force close MySQl from the Task Manager.
Delete the file with the SQL commands, and start again MySQL. The password must be changed now.
5.0
http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html
5.1
http://dev.mysql.com/doc/refman/5.1/en/resetting-permissions.html
... just change the version in the link (5.5, 5.6, 5.7)
In your "hostname".err file inside the data folder MySQL works on, try to look for a string that starts with:
"A temporary password is generated for roor#localhost "
you can use
less /mysql/data/dir/hostname.err
then slash command followed by the string you wish to look for
/"A temporary password"
Then press n, to go to the Next result.
I solved this a different way, this may be easier for some.
I did it this way because I tried starting in safe mode but cannot connect with the error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
What I did was to connect normally as root:
$ sudo mysql -u root
Then I created a new super user:
mysql> grant all privileges on *.* to 'myuser'#'%' identified by 'mypassword' with grant option;
mysql> quit
Then log in as myuser
$ mysql -u myuser -p -h localhost
Trying to change the password gave me no errors but did nothing for me so I dropped and re-created the root user
mysql> drop user 'root'#'localhost;
mysql> mysql> grant all privileges on *.* to 'root'#'localhost' identified by 'mypassword' with grant option;
The root user is now working with the new password
Using Debian / Ubuntu mysql packages, you can login with user debian-sys-maint, which has all the expected privileges, the password is stored in the file /etc/mysql/debian.cnf
Answers provided here did not seem to work for me, the trick turned out to be:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'test';
(complete answer here: Change user password in MySQL 5.7 with “plugin: auth_socket”)
System:
CentOS Linux 7
mysql Ver 14.14 Distrib 5.7.25
Procedure:
Open two shell sessions, logging in to one as the Linux root user
and the other as a nonroot user with access to the mysql command.
In your root session, stop the normal mysqld listener and start a
listener which bypasses password authentication (note: this is a
significant security risk as anyone with access to the mysql
command may access your databases without a password. You may want
to close active shell sessions and/or disable shell access before
doing this):
# systemctl stop mysqld
# /usr/sbin/mysqld --skip-grant-tables -u mysql &
In your nonroot session, log in to mysql and set the mysql root password:
$ mysql
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> quit;
In your root session, kill the passwordless instance of mysqld and restore the normal mysqld listener to service:
# kill %1
# systemctl start mysqld
In your nonroot session, test the new root password you configured above:
$ mysql -u root -p
Enter password:

I was stuck with this problem for a couple of minutes and the following was the only solution that actually worked:
https://phoenixnap.com/kb/access-denied-for-user-root-localhost
sudo mysql
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'insert_password';
mysql -u root -p
In case you already set a password in the past the mysql -uroot -p solution will not work,
In my case I used some of the answers above to solve this (Ubuntu 16). The result was:
sudo service mysql stop
sudo mysqld_safe --skip-grant-tables &
if you see this text in the screen:
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
then do:
sudo mkdir -p /var/run/mysqld
sudo chown mysql:mysql /var/run/mysqld
sudo mysqld_safe --skip-grant-tables & # Look at the & at the end!
Enter other terminal to set your password like this:
sudo mysql -u root
mysql> use mysql;
mysql> SET PASSWORD FOR 'root'#'localhost'=PASSWORD('__NEW__PASSWORD__');
mysql> flush privileges;
mysql> quit;
then restart the service and login
# end mysqld_safe in the other terminal
sudo service mysql start
sudo mysql -h 127.0.0.1 -uroot -p
For MySQL 5.5 on Windows 10
You can't find the password as it is hashed in the table, so resetting it is the only option.
The solution of importing the new password script by .txt file, as offered by Lokesh kumar Chippada, didn't work for me. I found that the command prompt just froze after initiating the import.
I added skip-grant-tables to the my.ini file as per the top the answer on this SO post by tonycoupland.
I was then able to login to mysql from the command line
$> mysql
and then in mysql
mysql> FLUSH PRIVILEGES;
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
See 'B.3.3.2.3 Resetting the Root Password: Generic Instructions' on mysql dev page. I have now removed skip-grant-tables from the my.ini file, and I can login as a root user using the new password I created.
Go to phpMyAdmin > config.inc.php > $cfg['Servers'][$i]['password'] = '';
For some reason MySQL stopped giving access for root. Uninstalled and reinstalled with Homebrew. Fresh install, fresh tables but when I enter
mysql -u root -p
I get this error:
Access denied for user 'root'#'localhost' (using password: NO)
I reinstalled MySQL five times but it is still asking for a password. How do I fix this?
None of these worked for me. I think i already had mysql somewhere on my computer so a password was set there or something. After spending hours trying every solution out there this is what worked for me:
$ brew services stop mysql
$ pkill mysqld
$ rm -rf /usr/local/var/mysql/ # NOTE: this will delete your existing database!!!
$ brew postinstall mysql
$ brew services restart mysql
$ mysql -uroot
all credit to #Ghrua
Just run this command (where NEWPASS is your password):
$(brew --prefix mysql)/bin/mysqladmin -u root password NEWPASS
I have had the same error and fixed it this way.
In case you have inadvertently set and forgot the root password, and you don't want to wipe all your databases and start over because you are lazy and forgot to have a back up solution in place, and you are using a fairly recent Homebrew install (Winter 2013), here are steps to reset your password for MySQL.
Stop the currently running MySQL instance
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Now start mysql by hand skipping the grant tables and networking
$(brew --prefix mysql)/bin/mysqld_safe --skip-grant-tables --skip-networking
Note that if when you run echo $(brew --prefix mysql) and it does not respond as "/usr/local/opt/mysql" in bash, you will need to adjust the path accordingly.
Once you have done this, you now should have a running, unprotected MySQL instance up.
Log in and set the password
mysql -u root
At the prompt, enter the following MySQL command to set a new password for the effected user.
mysql> update mysql.user set password=PASSWORD('new_password_here') WHERE user='root';
If all went to plan it should say:
Query OK, 1 row affected (0.02 sec)
Rows matched: 4 Changed: 1 Warnings: 0
Exit out of the MySQL prompt.
mysql> exit
Bye
Stop server:
mysqladmin -u root shutdown
Now, lets put back the launch daemon so we have our MySQL at the ready again:
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Congratulations. You've just reset your mysql root password. Pour yourself a coffee and get a backup solution in place!
I had the same problem a couple days ago. It happens when you install mysql via homebrew and run the initialization script (mysql_install_db) before starting the mysql daemon.
To fix it, you can delete mysql data files, restart the service and then run the initialization script:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
rm -r /usr/local/var/mysql/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
unset TMPDIR
mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
Got this error after installing mysql via home brew.
So first remove the installation. Then Reinstall via Homebrew
brew update
brew doctor
brew install mysql
Then restart mysql service
mysql.server restart
Then run this command to set your new root password.
mysql_secure_installation
Finally it will ask to reload the privileges. Say yes. Then login to mysql again. And use the new password you have set.
mysql -u root -p
If you run on Mojave, Catalina, Big Sur and now on macOS Monterey:
brew install mariadb
...
brew services start mariadb
==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)
$(brew --prefix mariadb)/bin/mysqladmin -u root password newpass
/usr/local/opt/mariadb/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'#'localhost''
also login with root account fails:
mariadb -u root
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
then default admin user is created same name as your MacOS account username, e.g. johnsmit.
To login as root and set root password, issue (use your username):
mariadb -u johnsmit

So you change root password form mysql on localhost.
Bonus: to change current or other user pass you can use mysqladmin command:
$(brew --prefix mariadb)/bin/mysqladmin -u arunas password 'newsecret'
but this does not affect localhost for some reason, but should work for app login.
Or use native MySQL change user password SQL, which explicitly specifies host, in my case 'localhost' account of the user:
mariadb -u arunas

Bye
Now let's try to login without password:
mariadb -u arunas
ERROR 1045 (28000): Access denied for user 'arunas'#'localhost' (using password: NO)
you see login failed, thus now we need specify the need of password:
mariadb -u arunas -p
Enter password:

Happy usage!
Since the question was asked/answered long time ago, those top answers do not work for me. Here's my solution, in 2020.
Background: Fresh mysql/mariadb installed by homebrew.
Problem: The password for root is not empty and unknown.
The fix:
mysql -u YOUR-SYSTEM-USERNAME -p
The password is empty (press enter)
ALTER USER 'root'#'localhost' IDENTIFIED BY 'NEW-ROOT-PASSWORD';
FLUSH PRIVILEGES;
The reason:
Homebrew will create a user with root privileges named by the current MacOS username.
it has no password
Since it has all privileges, just reset the root password with that user.
The initial password for root was randomly generated.
This worked for me:
sudo mysql -u root
If you are using macOS and install the MariaDB via Homebrew you can use the OS root password and then reset the password to whatever you want, in this case I removed the root's password:
sudo mysqladmin -u root password ''
or if you want to set a password you can put the password between the single quotations:
sudo mysqladmin -u root password 'NEW-PASSWORD-HERE'
Try with sudo to avoid the "Access denied" error:
sudo $(brew --prefix mariadb)/bin/mysqladmin -u root password NEWPASS
go to apple icon --> system preferences
open Mysql
in instances you will see "initialize Database"
click on that
you will be asked to set password for root --> set a strong password there
use that password to login in mysql from next time
Hope this helps.
I had this problem on a fresh install on Mac. I installed MariaDB with:
brew install mariadb
Then started the service:
brew services start mariadb
I was unable to run 'mysql_secure_installation' as it prompted for the root password. Then I noticed in the install output:
mysql_install_db --verbose --user=jonny --basedir=/usr/local/Cellar/ ....
So I tried logging in as the username specified in the mysql_install_db output and was successful e.g.
mysql -u jonny
Then at the mysql prompt if you want to set a password for the root user:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('ToPsEcReT');
I've just noticed something common to most of the answers here, and confirmed on my fresh install. It's actually obvious if you look at the recommendations to run mysqladmin -u root without -p.
There is no password.
Brew sets mysql up with just a root user and no password at all. This makes sense, I guess, but the post-install Caveats don't mention it at all.
This worked for me for MAC https://flipdazed.github.io/blog/osx%20maintenance/set-up-mysql-osx
Start mysql by running
brew services start mysql
Run the installation script
mysql_secure_installation
You will be asked to set up a setup VALIDATE PASSWORD plugin. Enter y to do this.
Select the required password validation (Doesn’t really matter if it is just you using the database)
Now select y for all the remaining options: Remove anon. users; disallow remote root logins; remove test database; reload privileges tables.
Now you should receive a message of
All done!
This worked for me. Hopefully this works for you too!!!
Follow them.
brew services stop mysql
pkill mysqld
# NB: the following command will REMOVE all your databases!
# Make sure you have backups or SQL dumps if you have important data in them already.
rm -rf /usr/local/var/mysql/
brew services restart mysql
mysql -uroot
UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;
exit;
mysql -u root
ALTER USER 'root'#'localhost' IDENTIFIED WITH caching_sha2_password
BY'YOUR_PASS_WORD!!!!';
Running these lines in the terminal did the trick for me and several others who had the same problem. These instructions are listed in the terminal after brew installs mysql sucessfully.
mkdir -p ~/Library/LaunchAgents
cp /usr/local/Cellar/mysql/5.5.25a/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
/usr/local/Cellar/mysql/5.5.25a/bin/mysqladmin -u root password 'YOURPASSWORD'
where YOURPASSWORD is the password for root.
Check that you don't have a .my.cnf hiding in your homedir. That was my problem.
The default password when you install mysql via brew is root try this, it worked for me
mysql -uroot -proot
So, in case someone has the same situation and configuration as I had and is also about to go mad - this worked for me.
After a long story I had a brew-installed MariaDB which kept automatically restarting when I killed its process (this was brew's doing), which had a root password, which I did not know.
$ brew services list
This shows something like:
mariadb started jdoe /path/to/homebrew.mxcl.mariadb.plist
Stop the MySQL server with:
$ brew services stop mariadb
Then start it again without the root user (and not using brew):
$ mariadbd --skip-grant-tables &
Here, mysql_secure_installation did not work for me because of the --skip-grant-tables, and it would not work without the --skip-grant-tables because it needed the password (which I did not have).
Trying $(brew --prefix mysql)/bin/mysqladmin -u root password hunter2 only returned strange errors and did nothing; $(brew --prefix mariadb)/bin/mysqladmin -u root password hunter2 also didn't work, gave different errors, and suggestions that did not work for me.
But you can log into mysql now without credentials: $ mysql
Here, the old method of updating the user table for root doesn't work because "Column 'Password' is not updatable".
The new method uses alter user BUT only works after you have done flush privileges; so do that first.
Then:
MariaDB [(none)]> alter user 'root'#'localhost' identified by 'hunter2';
(MariaDB [(none)]> is the MySQL prompt here)
Then do flush privileges; again.
Exit the MySQL client.
Now as far as brew is concerned, MariaDB is still not running, and so use $ ps aux | grep -i mariadb to find the pid and $ kill -9 <pid> it.
Then use $ brew services start mariadb to start it again.
I stumbled across this too and the solution was unironically to simply run this:
mysql
Terminal 1:
$ mysql_safe
Terminal 2:
$ mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD('new-password') WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
Iam using Catalina and use this mysql_secure_installation command and now works for me:
$ mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.
Enter current password for root (enter for none): << enter root here >>
i enter root as current password
OK, successfully used password, moving on...
Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.
and do the rest
For me, mysql was setup with a root user and no password.
I wanted to be able to login as my current user and not require the -u root bit. I used the following command to setup a super user:
mysql -u root -e "CREATE USER '$USER'#'localhost';"
mysql -u root -e "GRANT ALL PRIVILEGES ON *.* TO '$USER'#'localhost';"
mysql -u root -e "flush privileges;"
Any value for $USER will work.
I personally concatenated all the above with a semicolon but reformatted to make it hopefully easier for all to read.
Followed the article from #Roman Escart.
I guess the key is to use '$brew link --force mysql#5.7'
https://medium.com/macoclock/setup-mysql-in-a-specific-version-on-macos-35d8ad89c699
login to DB as root :
sudo mysql -u root
you may run secure db as:
sudo mysql_secure_installation
Use init file to start mysql to change the root password.
brew services stop mysql
pkill mysqld
echo "ALTER USER 'root'#'localhost' IDENTIFIED BY 'newRootPass';" > /tmp/mysql-init
$(brew --prefix mysql)/bin/mysqld --init-file=/tmp/mysql-init
Your root password is now changed. Make sure to shutdown server properly to save password change. In new terminal window execute
mysqladmin -u root -p shutdown
and enter your new pass.
Start your service and remove the init file
brew services start mysql
rm /tmp/mysql-init
Tested on mysql version 8.0.19
What is the easiest way to run Mysql on a Mac ?
My solution was to install MAMP.
https://www.mamp.info/en/mac/
I just installed MySQL on Mac OS X. The next step was setting the root user password, so I did this next:
Launch the terminal app to access the Unix command line.
Under the Unix prompt I executed these commands:
cd /usr/local/mysql/bin
./mysqladmin -u root password 'password'
But, when I execute the command
./mysql -u root, this is the answer:

I can get into the mysql command line without any password!
Why is this?
Try the command FLUSH PRIVILEGES when you log into the MySQL terminal. If that doesn't work, try the following set of commands while in the MySQL terminal
mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET password=PASSWORD("NEWPASSWORD") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
Change out NEWPASSWORD with whatever password you want. Should be all set!
Update: As of MySQL 5.7, the password field has been renamed authentication_string. When changing the password, use the following query to change the password. All other commands remain the same:
mysql> UPDATE user SET authentication_string=PASSWORD("NEWPASSWORD") WHERE User='root';
for MySQL 8.0+ Don't use
mysql> UPDATE mysql.user SET authentication_string='password' WHERE User='root';
as it overwrites the authentication_string, which is supposed to be a hash and not plain text, instead use:
mysql> `ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';`
If you don't remember the password you set for root and need to reset it, follow these steps:
Stop the mysqld server, this varies per install
Run the server in safe mode with privilege bypass
sudo mysqld_safe --skip-grant-tables;
In a new window connect to the database, set a new password and flush the permissions & quit:
mysql -u root
For MySQL older than MySQL 5.7 use:
UPDATE mysql.user SET Password=PASSWORD('your-password') WHERE User='root';
For MySQL 5.7+ use:
USE mysql;
UPDATE mysql.user SET authentication_string=PASSWORD("your-password") WHERE User='root';
Refresh and quit:
FLUSH PRIVILEGES;
\q
Stop the safe mode server and start your regular server back. The new password should work now. It worked like a charm for me :)
Note
Run
UPDATE mysql.user SET authentication_string=null WHERE User='root';
if you don't want to set a password for root user. Or if PASSWORD() function doesn't work for you.
Once you've installed MySQL, you'll need to establish the "root" password. If you don't establish a root password, then, well, there is no root password, and you don't need a password to log in.
So, that being said, you need to establish a root password.
Using terminal enter the following:
Installation: Set root user password:
/usr/local/mysql/bin/mysqladmin -u root password NEW_PASSWORD_HERE
If you've made a mistake, or need to change the root password use the following:
Change root password:
cd /usr/local/mysql/bin/
./mysql -u root -p
> Enter password: [type old password invisibly]
use mysql;
update user set password=PASSWORD("NEW_PASSWORD_HERE") where User='root';
flush privileges;
quit
The instructions provided in the mysql website is so clear, than the above mentioned
$ sudo /usr/local/mysql/support-files/mysql.server stop
$ sudo /usr/local/mysql/support-files/mysql.server start --skip-grant-tables
/usr/local/mysql/bin/mysql
mysql> FLUSH PRIVILEGES;
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
mysql> exit or Ctrl + z
$ sudo /usr/local/mysql/support-files/mysql.server stop
$ sudo /usr/local/mysql/support-files/mysql.server start
/usr/local/mysql/support-files/mysql -u root -p
Enter the new password i.e MyNewPass
Reference: http://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html
Stop the mysqld server.
Mac OS X: System Preferences → MySQL → Stop MySQL Server
Linux (From Terminal): sudo systemctl stop mysqld.service
Start the server in safe mode with privilege bypass
From Terminal: sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
In a new terminal window:
sudo /usr/local/mysql/bin/mysql -u root
This will open the MySQL command-line client. From here enter:
UPDATE mysql.user SET authentication_string=PASSWORD('NewPassword') WHERE User='root';
FLUSH PRIVILEGES;
quit
Stop the mysqld server again and restart it in normal mode.
Mac OS X (From Terminal): sudo /usr/local/mysql/support-files/mysql.server restart
Linux Terminal: sudo systemctl restart mysqld
For the new MySQL 5.7, for some reason the binary commands of MySQL aren't attached to the shell, and you have to do:
Restart the Mac after the installation.
Start MySQL:
System Preferences → MySQL → Start button
Go to MySQL install folder in the terminal:
cd /usr/local/mysql/bin/
Access to MySQL:
./mysql -u root -p
And enter the initial password given to the installation.
In the MySQL client, change the password:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPassword';
In the terminal, write mysql -u root -p and hit Return.
Enter the current MySQL password that you must have noted down.
And set the password:
SET PASSWORD = PASSWORD('new_password');
Please refer to this documentation here for more details.
If you have forgot the MySQL root password, can’t remember or want to break in….. you can reset the MySQL database password from the command line in either Linux or OS X as long as you know the root user password of the box you are on:
(1) Stop MySQL
sudo /usr/local/mysql/support-files/mysql.server stop
(2) Start it in safe mode:
sudo mysqld_safe --skip-grant-tables
(3) This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:
mysql -u root
UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
In the UPDATE command above just replace the 'password' with your own new password, make sure to keep the quotation marks
(4) Save and quite
FLUSH PRIVILEGES;
\q
(5) Start MySQL
sudo /usr/local/mysql/support-files/mysql.server start
I solved this by:
Shutting down my MySQL server: mysql.server stop
Running MySQL in safe mode: mysqld_safe --skip-grant-tables
In another terminal, login with mysql -u root
In the same terminal, run UPDATE mysql.user SET authentication_string=null WHERE User='root';, then FLUSH PRIVILEGES; and then exit with exit;
Stop the safe mode server with mysql.server stop and then start the normal one; mysql.server start
Now you can set your new password with
ALTER USER 'root'#'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
None of the previous comments solved the issue on my Mac.
I used the commands below and it worked.
brew services stop mysql
pkill mysqld
rm -rf /usr/local/var/mysql/ # NOTE: this will delete your existing database!!!
brew postinstall mysql
brew services restart mysql
mysql -u root
When I installed OS X v10.10 (Yosemite), I got a problem with MySQL. I tried lot of methods, but none worked. I actually found a quite easy way. Try this out.
First log in to a terminal from super user (su) privileges.
sudo su
Stop MySQL
sudo /usr/local/mysql/support-files/mysql.server stop
Start in safe mode:
sudo mysqld_safe --skip-grant-tables
Open another terminal, log in as su privileges, and then, log in to the MySQL client (mysql) without a password
mysql -u root
Change the password
UPDATE mysql.user SET Password=PASSWORD('new_password') WHERE User='root';
Flush privileges
FLUSH PRIVILEGES;
You are done now.
The methods mentioned in existing answers don't work for MySQL 5.7.6 or later. According the MySQL documentation, this is the recommended way.
B.5.3.2.3 Resetting the Root Password: Generic Instructions
MySQL 5.7.6 and later:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
Reference: https://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html
If you can't remember your password, #radtek's answer worked for me except in my case I had set up MySQL using brew which meant that steps 1 and 2 of his answer had to be changed to:
/usr/local/bin/mysql.server stop
/usr/local/bin/mysqld_safe --skip-grant-tables
Note: the lack of sudo.
I think this should work:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'YOURNEWPASSWORD'
(Note that you should probably replace root with your username if it isn't root.)
This is what exactly worked for me:
Make sure no other MySQL process is running. To check this do the
following:
From the terminal, run this command:
lsof -i:3306
If any PID is returned, kill it using kill -9 PID
Go to System Preferences → MySQL → check if any MySQL instances are running, stop them.
Start MySQL with the command:
sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
The password for every user is stored in the mysql.user table under columns User and authentication_string respectively. We can update the table as:
UPDATE mysql.user SET authentication_string='your_password' where User='root'
Stopping MySQL Server
sudo /usr/local/mysql/support-files/mysql.server stop
Starting MySQL in safe mode
sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables &
Changing the root password
/usr/local/mysql/bin/mysql -u root
use mysql;
UPDATE user SET authentication_string=PASSWORD('NEW_PASSWORD') WHERE user='root';
FLUSH PRIVILEGES;
exit
Testing
Run /usr/local/mysql/bin/mysql -u root
Now enter the new password to start using MySQL.
To reference MySQL 8.0.15 + , the password() function is not available. Use the command below.
Kindly use
UPDATE mysql.user SET authentication_string='password' WHERE User='root';
You can manually turn-off MySQL on Mac, by clicking on Apple menu and open System Preferences. Choose the “MySQL” preference panel, and then click on the “Stop MySQL Server” button to stop MySQL Server on Mac.
After you stop your MySQL, you'll need to follow these steps.
You'll need to start MySQL in skip-grant-tables mode
sudo /usr/local/mysql/support-files/mysql.server start --skip-grant-tables
In your terminal itself, enter this command to flush existing privileges
/usr/local/mysql/bin/mysql mysql> FLUSH PRIVILEGES;
Now you need to alter the user password
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'newpassword';
mysql> exit
Then you can go to Apple menu and open System Preferences. Choose the “MySQL” preference panel, then click on the “Stop MySQL Server” button to stop MySQL Server on Mac.
Finally you can again go to Apple menu and open System Preferences. Choose the “MySQL” preference panel, then click on the “Start MySQL Server” button to start MySQL Server on Mac.
This workaround works on my laptop!
Mac with macOS v10.14.5 (Mojave).
MySQL 8.0.17 was installed with Homebrew.
I run the following command to locate the path of MySQL
brew info mysql
Once the path is known, I run this:
/usr/local/Cellar/mysql/8.0.17/bin/mysqld_safe --skip-grant-table
In another terminal I run:
mysql -u root
Inside that terminal, I changed the root password using:
update mysql.user set authentication_string='NewPassword' where user='root';
and to finish I run:
FLUSH PRIVILEGES;
And voilà, the password was reset.
References
Try this in a terminal:
/usr/local/bin/mysql_secure_installation
macOS v10.14 (Mojave) and later with 5.7.26 installed from the Mac OS X DMG installer.
When attempting to use the UPDATE command posted by other users, it results in the following error:

In the second terminal window do the following:
4.1. Login to MySQL
mysql -u root
4.2. Run the following in the MySQL prompt:
FLUSH PRIVILEGES;
ALTER USER 'root'#'localhost' IDENTIFIED BY 'NEWPASSWORD';
4.3. Exit MySQL
exit;
Go back to the first terminal window and shutdown mysqld_safe
5.1. Press CTRL + Z
5.2. Run the following command
mysqladmin -u root -p shutdown
5.3. Enter the new password you set in 4.2. when prompted.
Start MySQL Server [see 1.]
If you forgot your password or want to change it to your MySQL:
Start your terminal and enter:
sudo su
Enter the password for you system
Stop your MySQL server:
sudo /usr/local/mysql/support-files/mysql.server stop
Leave this window open, run second terminal window and enter here:
mysql -u root
And change your password for MySQL:
UPDATE mysql.user SET authentication_string=PASSWORD('new_password') WHERE User='root';
where "new_password" - your new password. You don't need old password for MySQL.
Flush, quit and check your new password:
FLUSH PRIVILEGES;
Close all windows and check your new password for MySQL.
Much has changed for MySQL 8. I've found the following modification of the MySQL 8.0 "How to Reset the Root Password" documentation works with Mac OS X.
Create a temporary file, $HOME/mysql.root.txt, with the SQL to update the root password:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY '<new-password>';
This uses mysql_native_password to avoid the Authentication plugin 'caching_sha2_password' cannot be loaded error, which I get if I omit the option.
Stop the server, start with an --init-file option to set the root password, and then restart the server:
mysql.server stop
mysql.server start --init-file=$HOME/mysql.root.txt
mysql.server stop
mysql.server start
mysqld_safe --skip-grant-tables
mysql -u root
UPDATE mysql.user SET authentication_string='yourpasswd' WHERE User='root';
FLUSH PRIVILEGES;
ALTER USER 'root'#'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
I somehow need to do this every time my MacBook restarts.
$ export PATH=$PATH:/usr/local/mysql/bin
now,to make this permanent:
$ echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile
next, start mysql in safe mode:
$ sudo mysqld_safe --skip-grant-tables;
If this does not work, go to System Preferences and stop MySQL server.
next, On the **other** terminal, you may use the below:
$ mysql -u root
mysql> USE mysql;
mysql> UPDATE mysql.user SET authentication_string=null WHERE
User='root';
mysql> FLUSH PRIVILEGES;
mysql> exit;
$ mysql -u root
mysql> ALTER USER 'root'#'localhost' IDENTIFIED WITH
caching_sha2_password BY 'yourpassword';
$ mysql -u root -p
Enter password:
mysql> SELECT user();
next, start the mysql server in normal mode. and you're done with resetting your root password. this worked for mysql 8.0.17 ver. for me.

As of Dec 2022, the following works for MySQL 8.0.26 on macOS Big Sur 11.2.3 :
Go to system preferences > mysql > stop server
Open terminal and run: mysqld_safe --skip-grant-tables
Open a new terminal and run: mysql -u root
Run: ALTER USER 'root'#'localhost' IDENTIFIED BY 'ROOT';
ROOT will be your new password.
Run: FLUSH PRIVILEGES;
Run: exit
Go to system preferences > mysql > start server
