no_autocomplete.module in No Autocomplete 7

No_autocomplete.module.

This module adds the autocomplete=off attribute to selected key user forms. On a browser that respects this setting, it means that the browser will not try to autocomplete the password on the user login forms, or the whole user edit form.

Many browsers, including current Chrome as of this writing and LastPass do not respect this setting. But it can 1. Offer some security on the login form 2. Prevent naive users from getting the browser-fill on the first password form and not the second, making them angry and confused.
