One more step to unhitching from Google…
Right now the only option I see in F-Droid is Aegis.
I’m not sure what to actually look for side from checking for unexpected permissions and reasonably frequent updates.
Hopefully something I can sync with a GNOME app…
Definitely this, especially if you’ll be sharing with a non techie. My wife was able to pick 1password up and use it immediately and she normally turns her nose up at any of my recommendations.
For the 1password accounts 2FA, use a yubikey or aegis. Everything else to 1 password.
