I won’t be using Android for a few years till my Apple device dies (best phone is the one you have, right?). However, there is one app that you can use cross platform that I endorse completely: KeePassium .

Has a simple interface, supports password sharing between self hosted servers via standardized KeePass libraries, and has TOTP which eliminates the need for a second app. I use keepassXC on Fedora and it syncs wonderfully. Took a second to setup, but it’s the best password experience I’ve had thus far.
