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…
Right under Password in the edit screen of an item: Authenticator Key. You put in the auth key the target site provides you when you enable TOTP and it will start generating timed tokens. Usually you’ll also get a one-time pad of backup keys, I usually toss those in the Notes of the edit screen there as well in case something goes wrong.
The browser extension also lets you scan the page for QR codes for the TOTP key.
