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.

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+

It appears that Chrome now ignores autocomplete="off" unless it is on the <form autocomplete="off"> tag.

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

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?

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

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.

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();  }" />

// 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.

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

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).

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.

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.

Approved on:

• Chrome : 49


• Firefox : 44, 45


• Edge : 25


• Internet Explorer : 11

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:

1. The following at the top of the form:

<input style="display:none" type="text" name="fakeUsername"/>

<input style="display:none" type="password" name="fakePassword"/>

2. 
   

   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

Instead of autocomplete="off" use autocomplete="false" ;)

from: https://stackoverflow.com/a/29582380/75799

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

As of Chrome 42, none of the solutions/hacks in this thread (as of 2015-05-21T12:50:23+00:00) work for disabling autocomplete for an individual field or the entire form.

EDIT: I've found that you actually only need to insert one dummy email field into your form (you can hide it with display: none) before the other fields to prevent autocompleting. I presume that chrome stores some sort of form signature with each autocompleted field and including another email field corrupts this signature and prevents autocompleting.

<form action="/login" method="post">

    <input type="email" name="fake_email" style="display:none" aria-hidden="true">

    <input type="email" name="email">

    <input type="password" name="password">

    <input type="submit">

</form>

The good news is that since the "form signature" is corrupted by this, none of the fields are autocompleted, so no JS is needed to clear the fake fields before submission.

Old Answer:

The only thing I've found to be still viable is to insert two dummy fields of type email and password before the real fields. You can set them to display: none to hide them away (it isn't smart enough to ignore those fields):

<form action="/login" method="post">

    <input type="email" name="fake_email" style="display:none" aria-hidden="true">

    <input type="password" name="fake_password" style="display:none" aria-hidden="true">

    <input type="email" name="email">

    <input type="password" name="password">

    <input type="submit">

</form>

Unfortunately, the fields must be within your form (otherwise both sets of inputs are autofilled). So, for the fake fields to be truly ignored you'll need some JS to run on form submit to clear them:

form.addEventListener('submit', function() {

    form.elements['fake_email'].value = '';

    form.elements['fake_password'].value = '';

});

Notice from above that clearing the value with Javascript works to override the autocomplete. So if loosing the proper behavior with JS disabled is acceptable, you can simplify all of this with a JS autocomplete "polyfill" for Chrome:

(function(document) {



    function polyfillAutocomplete(nodes) {



        for(var i = 0, length = nodes.length; i < length; i++) {



            if(nodes[i].getAttribute('autocomplete') === 'off') {



                nodes[i].value = '';

            }

        }

    }



    setTimeout(function() {



        polyfillAutocomplete(document.getElementsByTagName('input'));

        polyfillAutocomplete(document.getElementsByTagName('textarea'));



    }, 1);



})(window.document);

After the chrome v. 34, setting autocomplete="off" at <form> tag doesn`t work

I made the changes to avoid this annoying behavior:

1. Remove the name and the id of the password input


2. 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.

After having tried all solutions, Here is what seems to be working for chrome version:45, with form having password field :

 jQuery('document').ready(function(){

        //For disabling Chrome Autocomplete

        jQuery( ":text" ).attr('autocomplete','pre'+Math.random(0,100000000));

 });

Change input type attribute to type="search".

Google doesn't apply auto-fill to inputs with a type of search.

I just updated to Chrome 49 and Diogo Cid's solution doesn't work anymore.

I made a different workaround hiding and removing the fields at run-time after the page is loaded.

Chrome now ignores the original workaround applying the credentials to the first displayed type="password" field and its previous type="text" field, so I have hidden both fields using CSS visibility: hidden;

<!-- HTML -->

<form>

    <!-- Fake fields -->

    <input class="chromeHack-autocomplete">

    <input type="password" class="chromeHack-autocomplete">



    <input type="text" placeholder="e-mail" autocomplete="off" />

    <input type="password" placeholder="Password" autocomplete="off" />

</form>



<!-- CSS -->

.chromeHack-autocomplete {

    height: 0px !important;

    width: 0px !important;

    opacity: 0 !important;

    padding: 0 !important; margin: 0 !important;

}



<!--JavaScript (jQuery) -->

jQuery(window).load(function() {

    $(".chromeHack-autocomplete").delay(100).hide(0, function() {

        $(this).remove();

    });

});

I know that it may seem not very elegant but it works.

In Chrome 48+ use this solution:

1. 
   

   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>
   
   

   
   


2. 
   

   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;
   
   }
   
   

   
   



3. You did it!

Also this will work for older versions.

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.

I've solved the endless fight with Google Chrome with the use of random characters.

<input name="name" type="text" autocomplete="rutjfkde">

Hope that it will help to other people.

autocomplete="off" works now, so you can just do the following:

<input id="firstName2" name="firstName2" autocomplete="off">

Tested in the current Chrome 70 as well as in all versions starting from Chrome 62.

Demo.

UPDATE: Since people tend to downvote this (see, for instance, a comment from @AntonKuznetsov down below) before reading the demonstration in the JSFiddle or actually looking into the JSFiddle's HTML, I have to express it clearly:

• the top input has the auto complete working


• 
  the bottom input has the auto complete disabled by adding autocomplete="off"
  

i found this solution to be the most appropriate:

function clearChromeAutocomplete()

{

// not possible, let's try: 

if (navigator.userAgent.toLowerCase().indexOf('chrome') >= 0) 

{

document.getElementById('adminForm').setAttribute('autocomplete', 'off'); 

setTimeout(function () {

        document.getElementById('adminForm').setAttribute('autocomplete', 'on'); 

}, 1500);

}

}

It must be loaded after dom ready, or after the form renders.

Whilst I agree autocomplete should be a user choice, there are times when Chrome is over-zealous with it (other browsers may be too). For instance, a password field with a different name is still auto-filled with a saved password and the previous field populated with the username. This particularly sucks when the form is a user management form for a web app and you don't want autofill to populate it with your own credentials.

Chrome completely ignores autocomplete="off" now. Whilst the JS hacks may well work, I found a simple way which works at the time of writing:

Set the value of the password field to the control character 8 ("x08" in PHP or  in HTML). This stops Chrome auto-filling the field because it has a value, but no actual value is entered because this is the backspace character.

Yes this is still a hack, but it works for me. YMMV.

I solved in another way. You can try this.

<input id="passfld" type="text" autocomplete="off" />

<script type="text/javascript">

// Using jQuery

$(function(){                                               

    setTimeout(function(){

        $("input#passfld").attr("type","password");

    },10);

});





// or in pure javascript

 window.onload=function(){                                              

    setTimeout(function(){  

        document.getElementById('passfld').type = 'password';

    },10);

  }   

</script>

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="nam​e or emai​l" autocomplete="off" />
