Improve password autofill capabilities

[fdocr]

Is your feature request related to a problem? Please describe.
Based on feedback from beta testers in TestFlight they want to have better password autofill capabilities when logging in

Describe the solution you'd like
The keyboard toolbar could be used to present suggested passwords, similar to how browsers handle it.

Describe alternatives you've considered
I'm not sure if autofill is possible directly in the form, that could be an option if it is indeed possible.

Additional context

I'm not able to get password autofill when logging in from iOS. Logging in via GitHub and Twitter have the same issue: I can go search for the right password, but it doesn't auto-detect which one I want
