Autocomplete on mobile browsers for username fields

Question

I'm looking for useful advice on whether autocomplete should be disabled or not on mobile browsers specifically for inputs in a username field.

I already have: <input type="email" name="signin-email" autocorrect="off" autocapitalize="off">

What is the current support for autocompleting email addresses and usernames?

Answer 1

Is there any specific reason to disable autocomplete?

if not, disabling that would add a 'little' dislike to your site.

Username should be enabled for autocompletion, Which is more true for mobile browsing, where typing is still quite challenging except the young users.

• Consider the major age category of your users. If that's over 25, typing on mobile is quite cumbersome. Add to that, someone may be using very small-display mobile.
• Usually, email-address is quite a long "word" to type in, where the mobile keyboard can't help with "auto-predict".
• A mobile is much more personal than a PC, so is its browser. So, filling up a username field wrongfully will be very rare.

Answer 2

I advise keeping autocomplete unless you/your users would be concerned about it for security reasons. In general, autocomplete is convenient for users so they don't need to waste time typing their info (especially on mobile).
