I don't know about you but does anyone else screenshot (and even print physical copies of, to keep safe) their authenticator barcodes given by websites, in case some day your chosen app dies or your phone(s)/tablets/everything gets lost?
I use Aegis, but also import the TOTP URI to pass, and use it with pass-otp[1].
It kind of defeats the purpose of 2FA, but I keep my pass repo relatively secure, and the convenience is worth it.
