    If you don't have the authenticator backup codes and you didn't turn on cloud sync in the app, you might be out of luck.

    You can get a replacement SIM though and use it with a new phone, so the phone number recovery option should work.

      This. Can't you get your number moved to a new phone? I have never don't anything magic when upgrading my phone other than move contacts.

        How would moving your number to a new phone help? We're talking TOTP here, not SMS "auth".

          does google not offer a backup via sms? it's a common enough recovery flow elsewhere. (i dont use google stuff, so i am genuinely asking)

            Any less secure backup method, means others are less secure.

              yes, i understand. i was asking specifically whether google has sms recovery flow, not how secure sms recovery flow is compared to other options.
