Is autocomplete="off" compatible with all modern browsers?

I've just been given a requirement to prevent browsers from saving data entered into specific form fields. It's been years since I've done web dev, and this is a relatively new capability. I was able to find the form field property autocomplete="off", but I can't seem to find any documentation indicating which browsers support it. Can anyone point me in the right direction of a chart of form attributes and browser compatibility?


Be aware that all major browsers are moving towards ignoring the attribute for password fields.

I can only offer anecdotal evidence, but I've yet to come across a browser that fails to respect autocomplete="off", this experience covers:

  • Firefox 1.5+ (Windows and Ubuntu)
  • Opera 6+ (Windows and Ubuntu)
  • Chrome v2+ (Windows and Ubuntu)
  • Epiphany 0.8 (ish) (Ubuntu)
  • Midori (I can't remember which version)
  • Safari v1+ (Windows)
  • IE 4 - 8, Windows.

I'm aware that Greasemonkey scripts, and presumably other user-scripts, can disable the autocomplete setting.

There's a couple of articles I found that might be useful to you:

  1. How to turn off form auto-completion
  2. Using auto-complete in html forms

Password managers now ignore the autocomplete attribute for password fields in the major browsers as of:

  • IE11
  • Firefox 30
  • Chrome 34
  • Safari seems to have an opt-in option to ignore them

It should still work fine for disabling autocomplete on form fields, but no longer affects the password manager.


As of Chrome v34, autocomplete="off" is now ignored by default.

This somewhat debatable feature can be disabled in the flags configuration by visiting chrome://flags

If you're able to use JavaScript and jQuery, you can place this on load of the html:

$('#theform input').val('');
