How to clear basic authentication details in chrome - google-chrome

I'm working on a site that uses basic authentication. Using Chrome I've logged in using the basic auth. I now want to remove the basic authentication details from the browser and try a different login.
How do you clear the current basic authentication details when using Chrome?

It seems chrome will always show you the login prompt if you include a username in the url e.g.
http://me#example.com
This is not a real full solution, see Mike's comment below.

You can open an incognito window Ctrl+Shift+n each time you are doing a test. The incognito window will not remember the username and password the last time you entered.
To use this trick, make sure to close all incognito windows. All incognito windows share the same cache. In other words, you cannot open multiple independent incognito windows. If you login in one of them and open another one, those two are related and you will see that the new window remembers the authentication information from the first window.

all you need to do is to type chrome://restart in the address bar and chrome, with all its apps that are running in background, will restart and the Auth password cache will be cleaned.

The authentication is cleared when you exit Chrome.
Note however, that by default Chrome is running apps in the background, so it may not really exit even if you close all Chrome windows. You can either change this behavior under advanced setting, or e.g. under Windows, you can completely exit Chrome by using the Chrome icon in the systray. There should be an icon if Chrome is still running, but maybe you'll find it only in the popup with the hidden icons. The context menu of the Chrome icon has an entry to completely exit Chrome, and you can also change the setting for running apps in the background using that menu.
Open the Chrome menu
Select Settings
Scroll to the bottom
Click Show advanced settings...
Scroll to the bottom
Under System uncheck the box labeled: Continue running background apps when Google Chrome is closed

function logout(url){
var str = url.replace("http://", "http://" + new Date().getTime() + "#");
var xmlhttp;
if (window.XMLHttpRequest) xmlhttp=new XMLHttpRequest();
else xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4) location.reload();
}
xmlhttp.open("GET",str,true);
xmlhttp.setRequestHeader("Authorization","Basic YXNkc2E6")
xmlhttp.send();
return false;
}

Right click on your Bookmark Bar -> Add Page...
Set the name as Logout Basic Auth
Set the URL as:
javascript: (function() {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4) {
location.reload()
}
};
xmlhttp.open("GET", location.origin, true);
xmlhttp.setRequestHeader("Authorization", "Basic aW52YWxpZDoK");
xmlhttp.send();
return false;
})()
On any webpage you need to logout of Basic Auth, click the bookmark.

This isn't exactly what the question is asking for but in case you accidentally saved basic auth credentials and want to clear them or update them:
https://support.google.com/accounts/answer/6197437
Open Chrome.
At the top right, click More > and then Settings.
At the bottom, click Advanced.
Under "Passwords and forms," click Manage passwords.
Under "Saved Passwords", click Remove on the site you want to clear saved basic auth credentials.
Steps 1-4 can be quickly navigated with this link: chrome://settings/passwords
This worked in Chrome Version 59.0.3071.115

There is no way to do this in Chrome as yet (Chrome 58)
I have found the best solution is to open the url in an Incognito window, which will force you to re-enter the basic authentication credentials.
When you want to change the credentials, close the Incognito window and launch another Incognito window.

Just do
https://newUsername:newPassword#example.com
...to override your old credentials.

I am using Chrome Version 83 and this is how I did it. Before following the steps make sure the tab of the site, whose Auth Details you want to delete is closed.
First, go to Settings >> Privacy and security.
Then click on Site settings option
Then click on View permissions and data stored across sites option
Search for the site whose Auth info you want to delete. In this example, I am using Stack Overflow.
Now click on the site and then click the Clear data button.
Now restart your browser and you will be asked for a fresh login. For restarting you can type chrome://restart in the address bar.

This is a quick trick.
For example you already input basic auth to url https://example.com by user1:password1. To clear it just open new tab then:
Goto: https://any:any#example.com then your password will be removed.
any:any is any string.

As mentioned by #SalCelli, chrome://restart works. However, this relaunches all the tabs.
Another method is to launch in incognito mode as suggested by CEGRD
However, if you could not like to restart & use incognito, on Chrome 86 (Mac), I found that the answer provided by #opsb & Mike only works with the below additional steps.
Enter the wrong username in the url without the resources
eg: if the url is http://mywebsite.com/resources/, it will not work if I enter http://wrong#mywebsite.com/resources/, but will work if I enter only http://wrong#mywebsite.com/
it clears the Basic Auth credentials
prompt for the credentials again
However, entering the valid credentials will not work, as in the background, chrome still send the wrong user as part of the url, even though the url appears right in the address bar When prompted for credentials you would need to Cancel, and click the address bar and reload the page from pressing enter. Now enter the correct password

May be old thread but thought of adding answer to help others.
I had the same issue with Advanced ReST Client App, I'm not able to clear basic authentication from Chrome neither from app. It simply stopped asking for credentials!
However, I managed to make it work by relaunching Chrome using About Google Chrome -> Relaunch.
Once Chrome is relaunched, when I accessed ReST service, it will ask for user name and password using basic authentication popup.
Hope this helps!

A lot of great suggestions here, I'll give the one that I found the most efficient:
Just change your password in the site. The old authentication will became outdated and Chrome will request it again.
Since I had a terminal open, I did a simple script to change the password and in two keypresses it were incremented.

Press the key combination Ctrl+Shift+Delete
You will see popup in chrome
Check the above options and click clear data and you are done.

I'm using Chrome 75. What I've found is that restarting Chrome doesn't work. But restarting Chrome AND opening the developer tools does work. I don't have any explanation why this should be.

In Chrome, on the right-hand side of the URL bar when you are at a password protected URL, you should see a small key symbol. Click the symbol and it will take you directly to the Password Management area where you can remove the entry. That will ensure you receive future prompts or have an opportunity to enter a new password and save it.
If you do not see the key symbol, that same Password Management area can be accessed by going to Chrome -> Settings -> Passwords and forms -> Manage Passwords. Or more simply, this URL – chrome://settings/passwords.

For Chrome 66 I found the relevant option under:
Top right ... menu -> More Tools -> Clear Browsing Data
Click the "Advanced" tab
Check the "Passwords" box (and uncheck others you don't want cleared)
Click "Clear Data"
Using a new Incognito window is probably easier, but for those times you forget and want to clear the saved password, this does the trick without having to restart Chrome (which also works)

For Windows 10: What worked for me was clearing the credentials in the Windows Credentials in the Credential Manager.

I was using LastPass password manager, deleting credentials in LastPass solved the issue.

Weirdest thing, but in my case, I was trying to access a page with basic auth and Chrome was sending invalid credentials without even prompting for it. After I logged out from my LastPass plugin, everything was back to normal. So I think LastPass is starting to support Basic Auth but it's not giving the option of what password to use, it looks like it's just sending a random password for a domain that matches (which is very problematic in my case).
Thought it might help someone.

In my case (Win Chrome v100) it worked when using https://#domain.com to delete the credentials. Verify in the dev tools and querying document.URL.

Chrome uses the same Internet Options as IE.
Try opening your Internet Options and removing the URL from "Trusted Sites." This should regenerate a 401 call for credentials when you restart the browser and visit the URL again.
You may need to remove it from "Intranet Sites" as well.

Things changed a lot since the answer was posted.
Now you will see a small key symbol on the right hand side of the URL bar.
Click the symbol and it will take you directly to the saved password dialog where you can remove the password.
Successfully tested in Chrome 49

You can also do it via the settings page, chrome://chrome/settings
Under The Hood
Advanced Settings
Passwords and Forms
Then click the link Manage saved passwords.

You should be able to clear your credentials from your browser via "Clear Browsing Data..." in chrome://settings/advanced

how to diagnose/fix chrome pop up warning to change password due to a data breach

I'm currently running an app on AWS elastic beanstalk, and recently I had an issue come up where when I tried to enter a password, this a google chrome pop up appeared that is the same as the image below. The password is encrypted and entered in a password-type field. I know this is a very general question, but would anyone have any advice in diagnosing why this issue came about (perhaps by looking at specific things in AWS console), and how to prevent it? Does this warning occur only when the user has entered a password that is common/used across multiple apps, and has nothing to do with the code the app is based on?
Searched and found this answer:
Important: You must be signed in to Chrome to get these notifications.

Chrome shows old SSL certificate

I use Let's encrypt certificates on the server. The certificates are automatically renewed and the server-config is updated.
Problem: When I open the web-page in Chrome, it shows that the certificate is valid, but the Certificate dialogue still shows the old certificate info (see Valid from dates):
When I open the page in incognito mode, the browser shows the correct/new certificate
Another odd thing:
after refreshing the page with CTRL+F5, Chrome shows the correct info
but when I now close the tab and open a new tab, the old info will be shown again!?
Questions:
Is this maybe a bug in Chrome? i.e. maybe it caches the certificate info for too long
Or is there something my web-page/server can do to update this info?
tl;dr
It turned out that the issue is related to the web-page being a PWA and that we had initially used a www-only cert.
Details:
when setting up the server we first created a www-only-certificate for e.g. www.myapp.com
but we forgot to include the naked-domain in the cert, so some hours later we created a new cert for myapp.com and www.myapp.com
the browsers that had already loaded the app had the issue described in the question
Result:
actually we just ignored the issue, because only few clients were affected and even for those, chrome does not show an error and the connection is still encrypted
for more details see this Let's Encrypt forum post

CTRL + SHIFT + DEL. Chrome will open up a new tab with a popup window titled Clear Browsing Data. Make sure that only the Cached images and files box is checked. Otherwise, you might accidentally clear your browsing history, saved passwords, cookies, and more:

How to auto-login website in chrome with saved password

Chrome is auto-filling the credentials, but not log me in until I click login. How to automate? (windows, non-google websites).
Using the Chrome Identity API you can have Chrome (on desktop and Android) automatically attempt to log in the user when they hit your page, even if their session has expired.
Following is a workflow diagram of how it works, but the details can be found in the Google Authentication API: Let the user automatically sign back in section:
It is not the browser's responsibility to auto-login to websites. This is the responsibility of the website you are accessing. The browser can remember form data and auto-fill for you, as can various extensions like LastPass.
However, in order to actually auto-login, you must first login to the website you are trying to access and enable the option they provide, often called 'Remember me?'. The website would typically use a cookie to store the credentials (securely with a hash + salt), and if the cookie still exists (not cleared from the browser or expired), and the hash of real password in database matches the one in the cookie, the website will auto-login.
You could force the browser to try and auto-login with extensions, which are essentially macros. You could try Auto Login or iMacros extensions for this. I would generally avoid this though.
Anyone else stumbling into this thread from a google search.... you can do this with autohotkey. If you browse to yourbankhere.com and chrome fills in the user/pass, you can have autohotkey perform a mousemove then a mouseclick to click the login button.

How to turn off windows integrated authentication in Chrome

I used to be able to disable windows integrated authentication by updating the settings in IE. Recently this no longer works. Has something changed in recent versions of chrome? Is there a new way to turn this off?
Chrome version 46.0.2490.71
I used to use this setting in IE
Internet Options -> Advanced -> uncheck 'Enable Windows Integrated Authentication'
I got this response from an internal admin and it seems to work.
I think the best we came up with was to create a shortcut to
chrome.exe on your desktop and modify the target of the shortcut to be
something like:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --auth-server-whitelist="_"
Edit: Corrected the path for misplaced backslashes. Note also the (x86), just in case.
Expanding on Daniel Trimble's answer, which worked for me:
I would like to help more people find this useful answer by adding a little more context. What is Integrated Windows Authentication, and why would you want to disable it?
Basically, Integrated Windows Authentication allows a browser such as Chrome to access credentials that are stored on your computer (for example, the password you use to log into your office computer) and use those same credentials to log you into a website (for example, a password-protected portion of your company's website). This occurs behind the scenes, without a visible password prompt.
The problem is that you may not want to be automatically logged into a particular website.
Example: I like to use Chrome as a test browser to see the "public" view of my company's website. Generally I log into our site in Firefox or IE, make changes there, and then view the site in Chrome to make sure my changes were "published" as intended.
Suddenly, one day, I could no longer stay signed out of my company's website in Chrome. Whenever I navigated to a password-protected page, instead of giving me a login prompt, Chrome would automatically sign me in to Microsoft SharePoint (my company's content-management system) and show me the "logged in" version of that page.
If something similar is happening to you, there are other, more obvious things you should try first. Start by clearing your saved passwords (Chrome menu button > Settings > Show advanced settings > Passwords and forms > Manage passwords).
Clearing my saved passwords didn't work for me, so I tried other things: cleared the cache, removed all cookies, reset Chrome's settings, uninstalled and reinstalled Chrome. I even visited a password-protected page in an Incognito window, but Chrome still signed me in automatically.
Finally I found this Stack Overflow page, which solved the problem. (Thank you, Daniel Trimble!) Integrated Windows Authentication was the culprit. IWA used to be turned off by default in Chrome; you had to enable it via a checkbox in your Internet Options (shared with IE). At some point in the recent past, Google apparently decided to enable IWA by default. The unfortunate part is that they did not provide an option under Chrome's Settings panel to disable it. At least there's this workaround!
How to disable Integrated Windows Authentication (IWA) for Chrome via Windows' Control Panel:
(This applies to both Internet Explorer and Chrome since Chrome uses system settings that are managed using Internet Explorer.)
Press Windows' Start button, type "Internet Options" to search, and click the one result, from the control panel
Go to the "Security" tab
Select "Local Intranet" and click on "Custom Level" button
Scroll to the "User Authentication" section at the bottom of the list and select "Prompt for user name and password"
Click Ok, Apply, and Ok to save changes
Close all instances of the IE browser to make the changes effective. Launch the browser again and access the application. A basic authentication challenge will be served.

I found out we had a windows policy that set the following registry key:
HKEY_CURRENT_USER\Software\Policies\Google\Chrome\AuthServerWhitelist
Deleting this key made Chrome prompt for a username and password for me.
More information about the registry keys.
Great and all the above answers work perfect.!
To add more -- I found that google chrome (version 68.0.3440.106) has the GUI option for Windows integrated authentication, just like in IE, this worked for me :)
goto chrome://settings/
Show advanced settings...
In the "Network" section, click on "Change proxy settings..."
Chrome opens the internet properties window
in the security tab
Select Local Intranet and Click on "Custom Level" button
Scroll to bottom of the window to User Authentication section, select "Prompt for user name and password"
Click Ok, Apply and Ok to save changes.
close existing session and start a new chrome session.

Why is Chrome calling the autocompleted url before validation?

I'm using an API on my website to send emails to the users and while testing my call I noticed I was receiving the email twice.
So the url looks like "localhost/api/sendEmail" and, at least on Chrome, when I'm on localhost and I start typing "/ap" the url is automatically completed.
And I can see on Fiddler that Chrome (well I think that's him) is actually calling it before I press Enter so the mail is sent, and when I press Enter it is of course sent a second time.
This is not a problem since it won't be directly callable by the end-user, but I was just wondering what is the purpose of this first call ? Is Chrome pre-calling the page to make it faster to load ? Can it cause problems in different situations? Can one prevent Chrome from behaving like this?
Again, not a problem at all, but I'm just wondering.
This is Google's prefetch feature, which loads the page quicker, assuming you execute the auto-completed URL.
You can disable this option in Google Chrome:
Settings > Advanced Settings > Privacy: (uncheck) Prefetch resources..
Update 2019
I came across a similar question on superuser, which I provided an updated answer for.
Disable page load prediction service
chrome://settings/ -> expand Advanced section
Disable NoState Prefetch
chrome://flags -> search for "nostate"
