Every password manager allow you to copy/paste your password. This is NOT a solution.

The clipboard is insecure and can be accessed by any app that is running.

It's not a secure solution, period end of story, to copy paste a password to a shared location on the device that all running processes can access.

I mean, there's the guide. I wouldn't put my passwords on the clipboard, personally.

Keepass2Android has a custom keyboard to auto-type usernames/passwords.
