Google Authenticator is a TOTP client. TOTP is an open spec.
If you use a different client, you can probably find one that will let you back up codes (I'm sure Authy supports TOTP). Also note that all you need for that backup is a "seed", which is a hash. IIRC Google Authenticator uses SQLite to store its data, I bet it's not hard to get the seeds out and back them up manually.
- solarkennedy 10y agoI wrote a program to extract the seeds out of the sqlite and back into QR codes for easy transfer. You are right it wasn't that hard: https://github.com/solarkennedy/tfa_auth_dump https://github.com/solarkennedy/tfa_auth_dump
- xorcist 10y agoDo you need to root your phone in order to extract the sqlite database?
