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…
We use yubikeys at work, far better then an OTP. Also I have 2 for home use, the only issue is I need to put 1 on some keys I carry as I sometimes need 1 and don’t have it.
