Something similar happened to me about a year ago when the Google Authenticator app automatically updated to a new version. I lost all my accounts in the update process. Definitely learned a few lessons there.

This nightmare is why I always backup MFA QR codes and use those to add them to an open source app which let's me backup the data elsewhere too. Sorry to hear that!

  Yep, any time I use an authenticator with an account I generate "backup codes" and keep them in my password manager. This saved me when I got a new phone and for some reason my Google Authenticator did not transfer to the new phone properly.

    > Google Authenticator did not transfer to the new phone properly. This seems to be my normal experience with a new phone for MFA apps. I’m doing something wrong. That and setting up email are so dreaded that I hold off updating.

      Switching from Android to iOS for a phone, I found that Microsoft Authenticator officially doesn't support this. You can't backup, you can't transfer. Everything is lost, please start anew.

    I think they finally managed that last year, but only by syncing to your Google account: https://security.googleblog.com/2023/04/google-authenticator-now-supports.html https://security.googleblog.com/2023/04/google-authenticator... … Yeah I'm not sure that's very good for a 2FA app either. Offline backups feel better for me. I use something else for 2FA.

  I’d be interested to hear details on that. I’ve been thinking of printing QR codes as backups.

    For crucial stuff, I take photos first and store them on my own nextcloud (with its own replication) and also copy them on a physical device. And my Android authenticator (andOTP) allows me to export encrypted backups (with password saved on password manager, ofc), which I then save on Dropbox. If it's a MFA I actually don't care much about (security-wise), I simply save the token on bitwarden so it autocompletes for me (it defeats most of the main point of "multi" FA but I don't care about it to begin with). Printing is not a bad idea, especially for backup, if you put them in a fire-proof safe or something. Make sure to give each a name to know which service they are for.

  I put my TOTPs in Google and Microsoft authenticators for double-redundancy. On two separate handsets. Then I have someone else I trust implicitly scan the QRs too and have them on their phone. I've been burned too many times.
