How do I prevent a form from suggesting auto-complete values, from previous entries or from saved information in Edge?
In the above image, the email input field is marked as autocomplete="false", but still in the right pane you can see the suggestion is populating.
When I add autocomplete=disabled to one field it seems it work, but when I add the attribute to all the inputs, it again starts displaying suggestions for every field.
What is the solution for this?
Add the aria-autocomplete="list" attribute to the input.
<input type="text" id="FirstName" name="attr1" aria-autocomplete="list">
Do not use any other value for the attribute.
According to your description, I reproduced the problem. I think your issue is caused by the "Save and fill personal info" setting being enabled in Edge.
If you navigate to edge://settings/personalinfo and disable this feature, you can see this behavior no longer exists.
Or you can also click the "Manage personal info" option in the picture you provided, and then disable it.
I did some simple tests and found that if you need to solve the problem from the code, you need to modify the name attribute of the form's related field.
Like this(do not use attribute values like name or email... and maybe there are others I am not aware of):
<label for="attr1">attr1:</label>
<input type="text" id="FirstName" name="attr1">
<label for="attr2">attr2 :</label>
<input type="text" id="LastName" name="attr2">
<label for="attr3">attr3 :</label>
<input type="email" id="Email" name="attr3" autocomplete="off">
<input type="submit">
I don't recommend this, because good naming helps you understand and maintain the code. Using proper attributes like name and email also helps your code be more accessible for screen readers or other assistive technology.
I have a few input fields on my website. There are few passwords saved for that website(Chrome Login Saved passwords). But the problem i am facing is that the email is appearing on the input field which is not for email i.e somewhere else on that same website. This is the input field code where i don't want chrome to autofill/autocomplete as it is not required here. I have tried autocomplete =off/false/new-password nothing worked.
<input type="text" ng-model="week_sco_topic" placeholder="Week SCO Topics" autocomplete="off">
When you click on the field above it shows the saved passwords for that website which is not required on this field.
I found the solution. The browser ignores autocomplete="off" unless it is in a form. Therefore, the code below removed the autofill suggestions.
<form autocomplete="off"><input type="text" ng-model="week_sco_topic" placeholder="Week SCO Topics"></form>
Google chrome ignores autocomplete="off" so you can try to make another input field above it to fool the browser
<input type="text" style="visibilty:hidden">
<input type="text" ng-model="week_sco_topic" placeholder="Week SCO Topics" autocomplete="off">

By suggestions, I mean the drop down menu appear when you start typing, and it's suggestions are based on what you've typed before:
For example, when I type 'a' in title field, it will give me a ton of suggestions which is pretty annoying.
How can this be turned off?
What you want is to disable HTML autocomplete Attribute.
Setting autocomplete="off" here has two effects:
It stops the browser from saving field data for later autocompletion
on similar forms though heuristics that vary by browser. It stops the
browser from caching form data in session history. When form data is
cached in session history, the information filled in by the user will
be visible after the user has submitted the form and clicked on the
Back button to go back to the original form page.

Here's an example how to do it.
<form action="#" autocomplete="on">
First name:<input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
E-mail: <input type="email" name="email" autocomplete="off"><br>
<input type="submit">
</form>
If it's on React framework then use as follows:
<input
id={field.name}
className="form-control"
type="text"
placeholder={field.name}
autoComplete="off"
{...fields}/>

Update
Here's an update to fix some browsers skipping "autocomplete=off" flag.
<form action="#" autocomplete="off">
First name: <input type="text" name="fname" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');"><br> Last name: <input type="text" name="lname" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');"><br> E-mail:
<input type="email" name="email" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');"><br>
<input type="submit">
</form>
On Chrome, the only method we could identify which prevented all form fills was to use autocomplete="new-password". Apply this on any input which shouldn't have autocomplete, and it'll be enforced (even if the field has nothing to do with passwords, e.g. SomeStateId filling with state form values). See this link on the Chromium bugs discussion for more detail.
Note that this only consistently works on Chromium-based browsers and Safari - Firefox doesn't have special handlers for this new-password (see this discussion for some detail).
Update: Firefox is coming aboard! Nightly v68.0a1 and Beta v67.0b5 (3/27/2019) feature support for the new-password autocomplete attribute, stable releases should be coming on 5/14/2019 per the roadmap.
Update in 2022: For input fields with a type of password, some browsers are now offering to generate secure passwords if you've specified autocomplete="new-password". There's currently no workaround if you want to suppress that behavior, but I'll update if one becomes available.
use autocomplete="off" attribute
Quote:IMPORTANT
Put the attribute on the <input> element,
NOT on the <form> element
Adding the two following attributes turn off all the field suggestions (tested on Chrome v85, Firefox v80 and Edge v44):
<input type="search" autocomplete="off">
I know it's been a while but if someone is looking for the answer this might help. I have used autocomplete="new-password" for the password field. and it solved my problem. Here is the MDN documentation.
This solution worked for me: Add readonly attribute.
Here's an update to fix some browsers skipping the
"autocomplete=off" flag.
<input type="text" name="lname" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');">
autocomplete = "new-password" does not work for me.
I built a React Form.
Google Chrome will autocomplete the form input based on the name attribute.
<input
className="scp-remark"
type="text"
name="remark"
id='remark'
value={this.state.remark}
placeholder="Remark"
onChange={this.handleChange}
/>
It will base on the "name" attribute to decide whether to autofill your form. In this example, name: "remark". So Chrome will autofill based on all my previous "remark" inputs.
<input
className="scp-remark"
type="text"
name={uuid()} //disable Chrome autofill
id='remark'
value={this.state.remark}
placeholder="Remark"
onChange={this.handleChange}
/>
So, to hack this, I give name a random value using uuid() library.
import uuid from 'react-uuid';
Now, the autocomplete dropdown list will not happen.
I use the id attribute to identify the form input instead of name in the handleChange event handler
handleChange = (event) => {
const {id, value} = event.target;
this.setState({
[id]: value,
})
}
And it works for me.
I had similar issue but I eventually end up doing
<input id="inp1" autocomplete="off" maxlength="1" />
i.e.,
autocomplete = 'off' and suggestions will be disappeared.
<input type="text" autocomplete="off"> is in fact the right answer, though for me it wasn't immediately clear.
According to MDN:
If a browser keeps on making suggestions even after setting
autocomplete to off, then you have to change the name attribute of the
input element.
The attribute does prevent the future saving of data but it does not necessarily clear existing saved data. Thus, if suggestions are still being made even after setting the attribute to "off", either:
rename the input
clear existing data entries
Additionally, if you are working in a React context the attribute naturally becomes autoComplete.
Cheers!
I ended up changing the input field to
<textarea style="resize:none;"></textarea>
You'll never get autocomplete for textareas.
If you are using ReactJS. Then make this as autoComplete="off"
<input type="text" autoComplete="off" />
I've created a web application which uses a tagbox drop down. This works great in all browsers except Chrome browser (Version 21.0.1180.89).
Despite both the input fields AND the form field having the autocomplete="off" attribute, Chrome insists on showing a drop down history of previous entries for the field, which is obliterating the tagbox list.
Prevent autocomplete of username (or email) and password:
<input type="email" name="email"><!-- Can be type="text" -->
<input type="password" name="password" autocomplete="new-password">
Prevent autocomplete a field (might not work):
<input type="text" name="field" autocomplete="nope">
Explanation:
autocomplete still works on an <input>despite having autocomplete="off", but you can change off to a random string, like nope.
Others "solutions" for disabling the autocomplete of a field (it's not the right way to do it, but it works):
1.
HTML:
<input type="password" id="some_id" autocomplete="new-password">
JS (onload):
(function() {
var some_id = document.getElementById('some_id');
some_id.type = 'text';
some_id.removeAttribute('autocomplete');
})();
or using jQuery:
$(document).ready(function() {
var some_id = $('#some_id');
some_id.prop('type', 'text');
some_id.removeAttr('autocomplete');
});
2.
HTML:
<form id="form"></form>
JS (onload):
(function() {
var input = document.createElement('INPUT');
input.type = 'text';
document.getElementById('form').appendChild(input);
})();
or using jQuery:
$(document).ready(function() {
$('<input>', {
type: 'text'
}).appendTo($('#form'));
});
To add more than one field using jQuery:
function addField(label) {
var div = $('<div>');
var input = $('<input>', {
type: 'text'
});
if(label) {
var label = $('<label>', {
text: label
});
label.append(input);
div.append(label);
} else {
div.append(input);
}
div.appendTo($('#form'));
}
$(document).ready(function() {
addField();
addField('Field 1: ');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form"></form>
Works in:
Chrome: 49+
Firefox: 44+
UPDATE
It seems now Chrome ignores the style="display: none;" or style="visibility: hidden; attributes.
You can change it to something like:
<input style="opacity: 0;position: absolute;">
<input type="password" style="opacity: 0;position: absolute;">
In my experience, Chrome only autocompletes the first <input type="password"> and the previous <input>. So I've added:
<input style="display:none">
<input type="password" style="display:none">
To the top of the <form> and the case was resolved.
It appears that Chrome now ignores autocomplete="off" unless it is on the <form autocomplete="off"> tag.
2021 UPDATE:Change <input type="text"> to <input type="search" autocomplete="off" >
That is all. Keeping the below answer around for nostalgia.
For a reliable workaround, you can add this code to your layout page:
<div style="display: none;">
<input type="text" id="PreventChromeAutocomplete"
name="PreventChromeAutocomplete" autocomplete="address-level4" />
</div>
Chrome respects autocomplete=off only when there is at least one other input element in the form with any other autocomplete value.
This will not work with password fields--those are handled very differently in Chrome. See https://code.google.com/p/chromium/issues/detail?id=468153 for more details.
UPDATE: Bug closed as "Won't Fix" by Chromium Team March 11, 2016. See last comment in my originally filed bug report, for full explanation. TL;DR: use semantic autocomplete attributes such as autocomplete="new-street-address" to avoid Chrome performing autofill.
Modern Approach
Simply make your input readonly, and on focus, remove it. This is a very simple approach and browsers will not populate readonly inputs. Therefore, this method is accepted and will never be overwritten by future browser updates.
<input type="text" onfocus="this.removeAttribute('readonly');" readonly />
The next part is optional. Style your input accordingly so that it does not look like a readonly input.
input[readonly] {
cursor: text;
background-color: #fff;
}
WORKING EXAMPLE
Well, a little late to the party, but it seems that there is a bit of misunderstanding about how autocomplete should and shouldn't work. According to the HTML specifications, the user agent (in this case Chrome) can override autocomplete:
https://www.w3.org/TR/html5/forms.html#autofilling-form-controls:-the-autocomplete-attribute
A user agent may allow the user to override an element's autofill field name, e.g. to change it from "off" to "on" to allow values to be remembered and prefilled despite the page author's objections, or to always "off", never remembering values. However, user agents should not allow users to trivially override the autofill field name from "off" to "on" or other values, as there are significant security implications for the user if all values are always remembered, regardless of the site's preferences.
So in the case of Chrome, the developers have essentially said "we will leave this to the user to decide in their preferences whether they want autocomplete to work or not. If you don't want it, don't enable it in your browser".
However, it appears that this is a little over-zealous on their part for my liking, but it is the way it is. The specification also discusses the potential security implications of such a move:
The "off" keyword indicates either that the control's input data is particularly sensitive (for example the activation code for a nuclear weapon); or that it is a value that will never be reused (for example a one-time-key for a bank login) and the user will therefore have to explicitly enter the data each time, instead of being able to rely on the UA to prefill the value for him; or that the document provides its own autocomplete mechanism and does not want the user agent to provide autocompletion values.
So after experiencing the same frustration as everyone else, I found a solution that works for me. It is similar in vein to the autocomplete="false" answers.
A Mozilla article speaks to exactly this problem:
https://developer.mozilla.org/en-US/docs/Web/Security/Securing_your_site/Turning_off_form_autocompletion
In some case, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really force the no-completion is to assign a random string to the attribute
So the following code should work:
autocomplete="nope"
And so should each of the following:
autocomplete="false"
autocomplete="foo"
autocomplete="bar"
The issue I see is that the browser agent might be smart enough to learn the autocomplete attribute and apply it next time it sees the form. If it does do this, the only way I can see to still get around the problem would be to dynamically change the autocomplete attribute value when the page is generated.
One point worth mentioning is that many browser will ignore autocomplete settings for login fields (username and password). As the Mozilla article states:
For this reason, many modern browsers do not support autocomplete="off" for login fields.
If a site sets autocomplete="off" for a form, and the form includes username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits this page.
If a site sets autocomplete="off" for username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits this page.
This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).
Finally a little info on whether the attribute belongs on the form element or the input element. The spec again has the answer:
If the autocomplete attribute is omitted, the default value corresponding to the state of the element's form owner's autocomplete attribute is used instead (either "on" or "off"). If there is no form owner, then the value "on" is used.
So. Putting it on the form should apply to all input fields. Putting it on an individual element should apply to just that element (even if there isn't one on the form). If autocomplete isn't set at all, it defaults to on.
Summary
To disable autocomplete on the whole form:
<form autocomplete="off" ...>
Or if you dynamically need to do it:
<form autocomplete="random-string" ...>
To disable autocomplete on an individual element (regardless of the form setting being present or not)
<input autocomplete="off" ...>
Or if you dynamically need to do it:
<input autocomplete="random-string" ...>
And remember that certain user agents can override even your hardest fought attempts to disable autocomplete.
TL;DR: Tell Chrome that this is a new password input and it won't provide old ones as autocomplete suggestions:
<input type="password" name="password" autocomplete="new-password">
autocomplete="off" doesn't work due to a design decision - lots of research shows that users have much longer and harder to hack passwords if they can store them in a browser or password manager.
The specification for autocomplete has changed, and now supports various values to make login forms easy to auto complete:
<!-- Auto fills with the username for the site, even though it's email format -->
<input type="email" name="email" autocomplete="username">
<!-- current-password will populate for the matched username input -->
<input type="password" autocomplete="current-password" />
If you don't provide these Chrome still tries to guess, and when it does it ignores autocomplete="off".
The solution is that autocomplete values also exist for password reset forms:
<label>Enter your old password:
<input type="password" autocomplete="current-password" name="pass-old" />
</label>
<label>Enter your new password:
<input type="password" autocomplete="new-password" name="pass-new" />
</label>
<label>Please repeat it to be sure:
<input type="password" autocomplete="new-password" name="pass-repeat" />
</label>
You can use this autocomplete="new-password" flag to tell Chrome not to guess the password, even if it has one stored for this site.
Chrome can also manage passwords for sites directly using the credentials API, which is a standard and will probably have universal support eventually.
Always working solution
I've solved the endless fight with Google Chrome with the use of random characters. When you always render autocomplete with random string, it will never remember anything.
<input name="name" type="text" autocomplete="rutjfkde">
Hope that it will help to other people.
Update 2022:
Chrome made this improvement: autocomplete="new-password" which will solve it but I am not sure, if Chrome change it again to different functionality after some time.
The solution at present is to use type="search". Google doesn't apply autofill to inputs with a type of search.
See: https://twitter.com/Paul_Kinlan/status/596613148985171968
Update 04/04/2016: Looks like this is fixed! See http://codereview.chromium.org/1473733008
Browser does not care about autocomplete=off auto or even fills credentials to wrong text field?
I fixed it by setting the password field to read-only and activate it, when user clicks into it or uses tab-key to this field.
fix browser autofill in: readonly and set writeble on focus (at mouse click and tabbing through fields)
<input type="password" readonly
onfocus="$(this).removeAttr('readonly');"/>
Update:
Mobile Safari sets cursor in the field, but does not show virtual keyboard. New Fix works like before but handles virtual keyboard:
<input id="email" readonly type="email" onfocus="if (this.hasAttribute('readonly')) {
this.removeAttribute('readonly');
// fix for mobile safari to show virtual keyboard
this.blur(); this.focus(); }" />
Live Demo https://jsfiddle.net/danielsuess/n0scguv6/
// UpdateEnd
By the way, more information on my observation:
Sometimes I notice this strange behavior on Chrome and Safari, when there are password fields in the same form. I guess, the browser looks for a password field to insert your saved credentials. Then it autofills username into the nearest textlike-input field , that appears prior the password field in DOM (just guessing due to observation). As the browser is the last instance and you can not control it, sometimes even autocomplete=off would not prevent to fill in credentials into wrong fields, but not user or nickname field.
Chrome version 34 now ignores the autocomplete=off,
see this.
Lots of discussion on whether this is a good thing or a bad thing? Whats your views?
You can use autocomplete="new-password"
<input type="email" name="email">
<input type="password" name="password" autocomplete="new-password">
Works in:
Chrome: 53, 54, 55
Firefox: 48, 49, 50
[Works in 2021 for Chrome(v88, 89, 90), Firefox, Brave, Safari]
The old answers already written here will work with trial and error, but most of
them don't link to any official doc or what Chrome has to say on this
matter.
The issue mentioned in the question is because of Chrome's autofill feature, and here is Chrome's stance on it in this bug link - https://bugs.chromium.org/p/chromium/issues/detail?id=468153#c164
To put it simply, there are two cases -
[CASE 1]: Your input type is something other than password. In this case, the solution is simple, and has three steps.
Add name attribute to input
name should not start with a value like email or username, otherwise Chrome still ends up showing the dropdown. For example, name="emailToDelete" shows the dropdown, but name="to-delete-email" doesn't. Same applies for autocomplete attribute.
Add autocomplete attribute, and add a value which is meaningful for you, like new-field-name
It will look like this, and you won't see the autofill for this input again for the rest of your life -
<input type="text/number/something-other-than-password" name="x-field-1" autocomplete="new-field-1" />
[CASE 2]: input type is password
Well, in this case, irrespective of your trials, Chrome will show you the dropdown to manage passwords / use an already existing password. Firefox will also do something similar, and same will be the case with all other major browsers. [1]
In this case, if you really want to stop the user from seeing the dropdown to manage passwords / see a securely generated password, you will have to play around with JS to switch input type, as mentioned in the other answers of this question.
[1] A detailed MDN doc on turning off autocompletion - https://developer.mozilla.org/en-US/docs/Web/Security/Securing_your_site/Turning_off_form_autocompletion
Autocomplete="Off" doesn't work anymore.
Try using just a random string instead of "Off", for example Autocomplete="NoAutocomplete"
I hope it helps.
I am posting this answer to bring an updated solution to this problem.
I am currently using Chrome 49 and no given answer work for this one.
I am also looking for a solution working with other browsers and previous versions.
Put this code on the beginning of your form
<div style="display: none;">
<input type="text" autocomplete="new-password">
<input type="password" autocomplete="new-password">
</div>
Then, for your real password field, use
<input type="password" name="password" autocomplete="new-password">
Comment this answer if this is no longer working or if you get an issue with another browser or version.

Seen chrome ignore the autocomplete="off", I solve it with a stupid way which is using "fake input" to cheat chrome to fill it up instead of filling the "real" one.
Example:
<input type="text" name="username" style="display:none" value="fake input" />
<input type="text" name="username" value="real input"/>
Chrome will fill up the "fake input", and when submit, server will take the "real input" value.
No clue why this worked in my case, but on chrome I used autocomplete="none" and Chrome stopped suggesting addresses for my text field.
Writing a 2020+ answer in case if this helps anyone. I tried many combinations above, though there is one key that was missed in my case. Even though I had kept autocomplete="nope" a random string, it didn't work for me because I had name attribute missing!
so I kept name='password'
and autocomplete = "new-password"
for username, I kept name="usrid" // DONT KEEP STRING THAT CONTAINS 'user'
and autocomplete = "new-password" // Same for it as well, so google stops suggesting password (manage password dropdown)
this worked very well for me.
(I did this for Android and iOS web view that Cordova/ionic uses)
<ion-input [type]="passwordType" name="password" class="input-form-placeholder" formControlName="model_password"
autocomplete="new-password" [clearInput]="showClearInputIconForPassword">
</ion-input>
autocomplete="off" is usually working, but not always. It depends on the name of the input field. Names like "address", 'email', 'name' - will be autocompleted (browsers think they help users), when fields like "code", "pin" - will not be autocompleted (if autocomplete="off" is set)
My problems was - autocomplete was messing with google address helper
I fixed it by renaming it
from
<input type="text" name="address" autocomplete="off">
to
<input type="text" name="the_address" autocomplete="off">
Tested in chrome 71.
Some end 2020 Update. I tried all the old solutions from different sites. None of them worked! :-(
Then I found this:
Use
<input type="search"/>
and the autocomplete is gone!
Success with Chrome 86, FireFox, Edge 87.
autocomplete=off is largely ignored in modern browsers - primarily due to password managers etc.
You can try adding this autocomplete="new-password" it's not fully supported by all browsers, but it works on some
to anyone looking for a solution to this, I finally figure it out.
Chrome only obey's the autocomplete="off" if the page is a HTML5 page (I was using XHTML).
I converted my page to HTML5 and the problem went away (facepalm).
Change input type attribute to type="search".
Google doesn't apply auto-fill to inputs with a type of search.
Up until just this last week, the two solutions below appeared to work for Chrome, IE and Firefox. But with the release of Chrome version 48 (and still in 49), they no longer work:
The following at the top of the form:
<input style="display:none" type="text" name="fakeUsername"/>
<input style="display:none" type="password" name="fakePassword"/>
The following in the password input element:
autocomplete="off"
So to quickly fix this, at first I tried to use a major hack of initially setting the password input element to disabled and then used a setTimeout in the document ready function to enable it again.
setTimeout(function(){$('#PasswordData').prop('disabled', false);}, 50);
But this seemed so crazy and I did some more searching and found #tibalts answer in Disabling Chrome Autofill. His answer is to use autocomplete="new-password" in the passwords input and this appears to work on all browsers (I have kept my fix number 1 above at this stage).
Here is the link in the Google Chrome developer discussion:
https://code.google.com/p/chromium/issues/detail?id=370363#c7
After the chrome v. 34, setting autocomplete="off" at <form> tag doesn`t work
I made the changes to avoid this annoying behavior:
Remove the name and the id of the password input
Put a class in the input (ex.: passwordInput )
(So far, Chrome wont put the saved password on the input, but the form is now broken)
Finally, to make the form work, put this code to run when the user click the submit button, or whenever you want to trigger the form submittion:
var sI = $(".passwordInput")[0];
$(sI).attr("id", "password");
$(sI).attr("name", "password");
In my case, I used to hav id="password" name="password" in the password input, so I put them back before trigger the submition.
I had a similar issue where the input field took either a name or an email. I set autocomplete="off" but Chrome still forced suggestions. Turns out it was because the placeholder text had the words "name" and "email" in it.
For example
<input type="text" placeholder="name or email" autocomplete="off" />
I got around it by putting a zero width space into the words in the placeholder. No more Chrome autocomplete.
<input type="text" placeholder="name or email" autocomplete="off" />
Instead of autocomplete="off" use autocomplete="false" ;)
from: https://stackoverflow.com/a/29582380/75799
In Chrome 48+ use this solution:
Put fake fields before real fields:
<form autocomplete="off">
<input name="fake_email" class="visually-hidden" type="text">
<input name="fake_password" class="visually-hidden" type="password">
<input autocomplete="off" name="email" type="text">
<input autocomplete="off" name="password" type="password">
</form>
Hide fake fields:
.visually-hidden {
margin: -1px;
padding: 0;
width: 1px;
height: 1px;
overflow: hidden;
clip: rect(0 0 0 0);
clip: rect(0, 0, 0, 0);
position: absolute;
}
You did it!
Also this will work for older versions.
I managed to disable autocomple exploiting this rule:
Fields that are not passwords, but should be obscured, such as credit
card numbers, may also have a type="password" attribute, but should
contain the relevant autocomplete attribute, such as "cc-number" or
"cc-csc".
https://www.chromium.org/developers/design-documents/create-amazing-password-forms
<input id="haxed" type="password" autocomplete="cc-number">
However it comes with the great responsibility :)
Don’t try to fool the browser Password managers (either built into the
browser, or external) are designed to ease the user experience.
Inserting fake fields, using incorrect autocomplete attributes or
taking advantage of the weaknesses of the existing password managers
simply leads to frustrated users.
Update 08/2022:
I managed to get autocomplete to be respected by including
autocomplete="new-password"
on each individual input element regardless of type.
E.g.
<input id="email" type="email" autocomplete="new-password"/>
How do you disable autocomplete in the major browsers for a specific input (or form field)?
Firefox 30 ignores autocomplete="off" for passwords, opting to prompt the user instead whether the password should be stored on the client. Note the following commentary from May 5, 2014:
The password manager always prompts if it wants to save a password. Passwords are not saved without permission from the user.
We are the third browser to implement this change, after IE and Chrome.
According to the Mozilla Developer Network documentation, the Boolean form element attribute autocomplete prevents form data from being cached in older browsers.
<input type="text" name="foo" autocomplete="off" />
In addition to setting autocomplete=off, you could also have your form field names be randomized by the code that generates the page, perhaps by adding some session-specific string to the end of the names.
When the form is submitted, you can strip that part off before processing them on the server-side. This would prevent the web browser from finding context for your field and also might help prevent XSRF attacks because an attacker wouldn't be able to guess the field names for a form submission.
Most of the major browsers and password managers (correctly, IMHO) now ignore autocomplete=off.
Why? Many banks and other "high security" websites added autocomplete=off to their login pages "for security purposes" but this actually decreases security since it causes people to change the passwords on these high-security sites to be easy to remember (and thus crack) since autocomplete was broken.
Long ago most password managers started ignoring autocomplete=off, and now the browsers are starting to do the same for username/password inputs only.
Unfortunately, bugs in the autocomplete implementations insert username and/or password info into inappropriate form fields, causing form validation errors, or worse yet, accidentally inserting usernames into fields that were intentionally left blank by the user.
What's a web developer to do?
If you can keep all password fields on a page by themselves, that's a great start as it seems that the presence of a password field is the main trigger for user/pass autocomplete to kick in. Otherwise, read the tips below.
Safari notices that there are 2 password fields and disables autocomplete in this case, assuming it must be a change password form, not a login form. So just be sure to use 2 password fields (new and confirm new) for any forms where you allow
Chrome 34, unfortunately, will try to autofill fields with user/pass whenever it sees a password field. This is quite a bad bug that hopefully, they will change the Safari behavior. However, adding this to the top of your form seems to disable the password autofill:
<input type="text" style="display:none">
<input type="password" style="display:none">
I haven't yet investigated IE or Firefox thoroughly but will be happy to update the answer if others have info in the comments.
Sometimes even autocomplete=off would not prevent to fill in credentials into the wrong fields, but not a user or nickname field.
This workaround is in addition to apinstein's post about browser behavior.
Fix browser autofill in read-only and set writable on focus (click and tab)
<input type="password" readonly
onfocus="this.removeAttribute('readonly');"/>
Update:
Mobile Safari sets cursor in the field, but it does not show the virtual keyboard. The new fix works like before, but it handles the virtual keyboard:
<input id="email" readonly type="email" onfocus="if (this.hasAttribute('readonly')) {
this.removeAttribute('readonly');
// fix for mobile safari to show virtual keyboard
this.blur(); this.focus(); }" />

Because the browser auto fills credentials to wrong text field!?
I notice this strange behavior on Chrome and Safari, when there are password fields in the same form. I guess the browser looks for a password field to insert your saved credentials. Then it auto fills (just guessing due to observation) the nearest textlike-input field, that appears prior the password field in the DOM. As the browser is the last instance and you can not control it.
This readonly-fix above worked for me.
The solution for Chrome is to add autocomplete="new-password" to the input type password. Please check the example below.
Example:
<form name="myForm"" method="post">
<input name="user" type="text" />
<input name="pass" type="password" autocomplete="new-password" />
<input type="submit">
</form>
Chrome always autocomplete the data if it finds a box of type password, just enough to indicate for that box autocomplete = "new-password".
This works well for me.
Note: make sure with F12 that your changes take effect. Many times, browsers save the page in the cache, and this gave me a bad impression that it did not work, but the browser did not actually bring the changes.
<form name="form1" id="form1" method="post"
autocomplete="off" action="http://www.example.com/form.cgi">
This will work in Internet Explorer and Mozilla Firefox. The downside is that it is not XHTML standard.
As others have said, the answer is autocomplete="off".
However, I think it's worth stating why it's a good idea to use this in certain cases as some answers to this and duplicate questions have suggested it's better not to turn it off.
Stopping browsers storing credit card numbers shouldn't be left to users. Too many users won't even realize it's a problem.
It's particularly important to turn it off on fields for credit card security codes. As this page states:
"Never store the security code ... its value depends on the presumption that the only way to supply it is to read it from the physical credit card, proving that the person supplying it actually holds the card."
The problem is, if it's a public computer (cyber cafe, library, etc.), it's then easy for other users to steal your card details, and even on your own machine a malicious website could steal autocomplete data.
Always working solution
I've solved the endless fight with Google Chrome with the use of random characters. When you always render autocomplete with random string, it will never remember anything.
<input name="name" type="text" autocomplete="rutjfkde">
Hope that it will help to other people.
Update 2022:
Chrome made this improvement: autocomplete="new-password" which will solve it but I am not sure, if Chrome change it again to different functionality after some time.
I'd have to beg to differ with those answers that say to avoid disabling auto-complete.
The first thing to bring up is that auto-complete not being explicitly disabled on login form fields is a PCI-DSS fail. In addition, if a users' local machine is compromised then any autocomplete data can be trivially obtained by an attacker due to it being stored in the clear.
There is certainly an argument for usability, however there's a very fine balance when it comes to which form fields should have autocomplete disabled and which should not.
Three options:
First:
<input type='text' autocomplete='off' />
Second:
<form action='' autocomplete='off'>
Third (JavaScript code):
$('input').attr('autocomplete', 'off');
This works for me.
<input name="pass" type="password" autocomplete="new-password" />
We can also use this strategy in other controls like text, select etc
In addition to
autocomplete="off"
Use
readonly onfocus="this.removeAttribute('readonly');"
for the inputs that you do not want them to remember form data (username, password, etc.) as shown below:
<input type="text" name="UserName" autocomplete="off" readonly
onfocus="this.removeAttribute('readonly');" >
<input type="password" name="Password" autocomplete="off" readonly
onfocus="this.removeAttribute('readonly');" >
On a related or actually, on the completely opposite note -
"If you're the user of the aforementioned form and want to re-enable
the autocomplete functionality, use the 'remember password'
bookmarklet from this bookmarklets
page. It removes
all autocomplete="off" attributes from all forms on the page. Keep
fighting the good fight!"
Just set autocomplete="off". There is a very good reason for doing this: You want to provide your own autocomplete functionality!
None of the solutions worked for me in this conversation.
I finally figured out a pure HTML solution that doesn't require any JavaScript, works in modern browsers (except Internet Explorer; there had to at least be one catch, right?), and does not require you to disable autocomplete for the entire form.
Simply turn off autocomplete on the form and then turn it ON for any input you wish it to work within the form. For example:
<form autocomplete="off">
<!-- These inputs will not allow autocomplete and Chrome
won't highlight them yellow! -->
<input name="username" />
<input name="password" type="password" />
<!-- This field will allow autocomplete to work even
though we've disabled it on the form -->
<input name="another_field" autocomplete="on" />
</form>
I've been trying endless solutions, and then I found this:
Instead of autocomplete="off" just simply use autocomplete="false"
As simple as that, and it works like a charm in Google Chrome as well!
We did actually use sasb's idea for one site.
It was a medical software web app to run a doctor's office. However, many of our clients were surgeons who used lots of different workstations, including semi-public terminals. So, they wanted to make sure that a doctor who doesn't understand the implication of auto-saved passwords or isn't paying attention can't accidentally leave their login information easily accessible.
Of course, this was before the idea of private browsing that is starting to be featured in Internet Explorer 8, Firefox 3.1, etc. Even so, many physicians are forced to use old school browsers in hospitals with IT that won't change.
So, we had the login page generate random field names that would only work for that post. Yes, it's less convenient, but it's just hitting the user over the head about not storing login information on public terminals.
I think autocomplete=off is supported in HTML 5.
Ask yourself why you want to do this though - it may make sense in some situations but don't do it just for the sake of doing it.
It's less convenient for users and not even a security issue in OS X (mentioned by Soren below). If you're worried about people having their passwords stolen remotely - a keystroke logger could still do it even though your app uses autcomplete=off.
As a user who chooses to have a browser remember (most of) my information, I'd find it annoying if your site didn't remember mine.
The best solution:
Prevent autocomplete username (or email) and password:
<input type="email" name="email"><!-- Can be type="text" -->
<input type="password" name="password" autocomplete="new-password">
Prevent autocomplete a field:
<input type="text" name="field" autocomplete="nope">
Explanation:
autocomplete continues work in <input>, autocomplete="off" does not work, but you can change off to a random string, like nope.
Works in:
Chrome: 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63 and 64
Firefox: 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57 and 58
Use a non-standard name and id for the fields, so rather than "name" have "name_". Browsers will then not see it as being the name field.
The best part about it is that you can do this to some, but not all, fields and it will autocomplete some, but not all fields.
Adding autocomplete="off" is not going to cut it.
Change the input type attribute to type="search".
Google doesn't apply auto-fill to inputs with a type of search.
I just ran into this problem and tried several failures, but this one works for me (found on MDN):
In some cases, the browser will keep suggesting autocompletion values
even if the autocomplete attribute is set to off. This unexpected
behavior can be quite puzzling for developers. The trick to really
force the no-completion is to assign a random string to the attribute
like so:
autocomplete="nope"
Adding the
autocomplete="off"
to the form tag will disable the browser autocomplete (what was previously typed into that field) from all input fields within that particular form.
Tested on:
Firefox 3.5, 4 BETA
Internet Explorer 8
Chrome
So here is it:
function turnOnPasswordStyle() {
$('#inputpassword').attr('type', "password");
}
<input oninput="turnOnPasswordStyle()" id="inputpassword" type="text">
In order to avoid the invalid XHTML, you can set this attribute using JavaScript. An example using jQuery:
<input type="text" class="noAutoComplete" ... />
$(function() {
$('.noAutoComplete').attr('autocomplete', 'off');
});
The problem is that users without JavaScript will get the autocomplete functionality.
This is a security issue that browsers ignore now. Browsers identify and store content using input names, even if developers consider the information to be sensitive and should not be stored.
Making an input name different between 2 requests will solve the problem (but will still be saved in browser's cache and will also increase browser's cache).
Asking the user to activate or deactivate options in their browser's settings is not a good solution. The issue can be fixed in the backend.
Here's the fix. All autocomplete elements are generated with a hidden input like this:
<?php $r = md5(rand() . microtime(TRUE)); ?>
<form method="POST" action="./">
<input type="text" name="<?php echo $r; ?>" />
<input type="hidden" name="__autocomplete_fix_<?php echo $r; ?>" value="username" />
<input type="submit" name="submit" value="submit" />
</form>
The server then processes the post variables like this: (Demo)
foreach ($_POST as $key => $val) {
$newKey = preg_replace('~^__autocomplete_fix_~', '', $key, 1, $count);
if ($count) {
$_POST[$val] = $_POST[$newKey];
unset($_POST[$key], $_POST[$newKey]);
}
}
The value can be accessed as usual
echo $_POST['username'];
And the browser won't be able to suggest information from the previous request or from previous users.
This will continue to work even if browsers update their techniques to ignore/respect autocomplete attributes.
Try these too if just autocomplete="off" doesn't work:
autocorrect="off" autocapitalize="off" autocomplete="off"
I can't believe this is still an issue so long after it's been reported. The previous solutions didn't work for me, as Safari seemed to know when the element was not displayed or off-screen, however the following did work for me:
<div style="height:0px; overflow:hidden; ">
Username <input type="text" name="fake_safari_username" >
Password <input type="password" name="fake_safari_password">
</div>
None of the hacks mentioned here worked for me in Chrome.
There's a discussion of the issue here: https://code.google.com/p/chromium/issues/detail?id=468153#c41
Adding this inside a <form> works (at least for now):
<div style="display: none;">
<input type="text" id="PreventChromeAutocomplete" name="PreventChromeAutocomplete" autocomplete="address-level4" />
</div>
Things had changed now as I tried it myself old answers no longer work.
Implementation that I'm sure it will work. I test this in Chrome, Edge and Firefox and it does do the trick. You may also try this and tell us your experience.
set the autocomplete attribute of the password input element to "new-password"
<form autocomplete="off">
....other element
<input type="password" autocomplete="new-password"/>
</form>
This is according to MDN
If you are defining a user management page where a user can specify a new password for another person, and therefore you want to prevent autofilling of password fields, you can use autocomplete="new-password"
This is a hint, which browsers are not required to comply with. However modern browsers have stopped autofilling <input> elements with autocomplete="new-password" for this very reason.
