Google Authenticator implements TOTP, which is actually a very simple standard: https://pthree.org/2014/04/15/time-based-one-time-passwords-... If you can extract the private key, you can transfer it to another phone or device. On Android, AndOTP is open source (available on F-Droid) and allows encrypted backups. As for Google Authenticator, I don't think you can create backups. |
