I’ve spent over an hour searching this site for the definitive word on whether autofill is supposed to actually fill in the user name and password to log into a site. I’ve seen some suggestions that developers, for security reasons, require one to click to fill in the login form.
Because it is non-intuitive that autofill doesn’t actually fill, this is a topic that should be covered by the Desktop FAQ. It would help me to hear from the developers how this function is supposed to work.
Hint: If by design, it doesn’t actually fill anything, perhaps you need to better communicate how this function is supposed to work.
