It’s time for me to move from SMS to a 2FA Authenticator app. I want something that will be open source but also ridiculously easy to back up, transfer to a new device, or replace if it is on a device that fails. I want it to be versatile enough to use across all necessary authentications. I also want to be sure that I can use the same app for many many years. I don’t want it tied into another service.
What’s my best option?
I’m pretty happy with Aegis. AFAIK, it doesn’t work with any of the “push” style methods (Duo, MS Auth, etc), but I don’t care for those anyway. Easy to backup/restore, the backups are encrypted, you can lock the app behind a password/PIN and/or biometric lock, and it’s open source.
