Stop browser from auto filling the form username and password fields

Question

In the Chrome browser, I have saved the username and the password.

Now, if I navigate to some other form and it contains the username and password for some other stuff, the one I saved is auto-populated here.

How can I stop this?

Answer 1

When autocomplete=off would not prevent to fill in credentials, use following -

fix browser autofill in: readonly and set writeble on focus (click and tab).

 <input type="password" readonly onfocus="this.removeAttribute('readonly');" onblur="this.setAttribute('readonly','');"/>

Answer 2

For Fire fox browser use this:

<input type="text" name="prevent_autofill" id="prevent_autofill" value="" style="display:none;" />
<input type="password" name="password_fake" id="password_fake" value="" style="display:none;" />
<input type="password" name="password" id="password" value="" />

For Chrome browser: use autocomplete="new-password"

Please refer to the following:
https://www.chromium.org/developers/design-documents/create-amazing-password-forms and https://www.chromium.org/developers/design-documents/form-styles-that-chromium-understands

Try the following :

<form id="login" action="signup.php" method="post">
    <input type="text" autocomplete="username">
    <input type="password" autocomplete="new-password">
    <input type="password" autocomplete="new-password">
    <input type="submit" value="Sign Up!">
</form>
