No recovery options, use Authy
It works and served me well for a long time, but I recently upgraded my phone which meant I had to go through every website that I was using this with and disable and then re-enable two factor authentication to register the new Authenticator app. This is akin to having to change every password for every site managed by a password manager when changing phones. It’s an awful experience and wastes so much time.
Unlike other Authenticator apps, this one is not protected by TouchID or FaceID and does not give you the ability to recover serial numbers for migration purposes.
Luckily for one site I had used Authy instead, I opened up the Authy app and it asked me if I wanted to add the new device to my Authy account, I tapped yes, tapped allow on my old phone and everything transferred perfectly.
Every app/site that was using Google Authenticator is now using Authy and I couldn’t be happier.
