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.

I personally use Ente Auth and quite like it, don’t use syncing and save an encrypted copy to my PC. I really like that you can see what the next code will be.
