Oh wow that would be really bad (not catastrophic since again I could recover Google with backup codes and from there email recovery for the other accounts).

I heard good things about Authy but I've been a bit cautious to add yet another service (which sounds ironic considering the 430 accounts I originally mentioned) just for what it seems like a simple TOTP client, and I don't need any other fancy feature such as cross-device sharing because of the above mentioned recovery procedure always being available in extreme cases.

Plus I was under the assumption that Authenticator data was backed up via iOS backups or iOS keyring, but I admit I've never tried it so I'm just speculating.
