There’s also Enpass (https://www.enpass.io/) which markets itself as an offline password manager.
1) How's it do at syncing / conflicts?
2) In the Android app, do you know if there's a way to use the fingerprint feature without storing your master password or an encrypted derivative of it to non-volatile memory?
For those scratching their heads at #2, it's motivated by my lukewarm trust of vendor-implemented components of Android Keystore. Some competing apps address it by making you authenticate with the full password the first time after boot (or after the app is closed by the user / memory management system / configurable timeout) and just tie your fingerprint to an "unlock" pin of sorts that only works when the database is "hot".
Regarding 2), no I don't know but good question. Using the same master password is annoying as you don't type the same on mobile
I know the Android Lastpass client would often prompt for a Master Password if it hadn't been used in a while, then let Fingerprints unlock it. I assumed it did something similar but haven't deep-dived the implementation.
