Keepass2 and keepass2android combined with input stick to type my passwords wherever I need them. It’s a wonderful combination. I host my password file on Google drive and other places but I keep a key file on the local device. It’s not perfect and wouldn’t never stop a threat from a state actor but I don’t think I’ve got time for that kind of security anyway.

Incidentally the input stick can function as an on the fly rubber ducky if you really want it to. It does some really really cool stuff.
