Earlier quoted context omitted.
It would be really cool if you could plug your phone in and it appeared as a USB keyboard device and you could "type" the password from the password manager that way without ever giving the computer access to anything except that password. Maybe some sort of simple USB dongle (like a yubikey) could be fed by the phone via bluetooth or nfc to do this?
It would be even cooler if I could open an app on my phone, point it at a QR code on screen, and not have anything else bother me
Unfortunately I don't see the need to actually fill and type passwords going away any time soon.
I'm mostly complaining about having to either:
1) Install the password manager on a computer to fill in passwords. You end up typing the password manager's password into the computer which could compromise the entire database as well as give the computer other information about your accounts and website usage.
2) Otherwise you have a password manager on your phone. You have to view the password and type it into a keyboard. Typing complex passwords is a pain in the butt. It would be nice if the password manager on my phone could just somehow type it for me. Then the only thing that goes into the computer is the exact password I'm trying to use.
