Rejoice! Our beloved password manager, ZX2C4’s pass, sees its Android implementation back on F-Droid. This APS fork has been pushing development forward since some time already, and has finally been published on the aforementioned app store earlier this month.
I don’t have any experience with bitwarden. The question is what do you want.
I like pass because I can host my password with git, a decentralised storage. I have to manage the key myself.
