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…
This is the way. I use Bitwarden and Aegis.
The issue here is putting Bitwarden on your phone with OTP in Bitwarden.
