This is a problem with Google authenticator, not with RFC 6238 TOTP in general. Plenty of authenticator apps support backing up your secrets.

Indeed. I’m trying to move from Google Authenticator to Authy for that reason - but the inability to backup/export from GA is a PITA... a cruel form of vendor lock-in.

If you are switching authenticator apps, I would suggest switching to one that respects your freedom, such as Aegis, andOTP, or KeePass.

It's worth also noting that Authy also has no official way to export your secrets, although there are workarounds: https://tij.me/blog/migrating-your-one-time-passwords-from-a...
