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…
I use Aegis, automatically backed up every time a new key is added. Was using Authy for a while, but they’re going down the enshittification hole, so I dumped them.
