EDIT: You know, after some time to cool off, Google Authenticator 2FA can still be enabled and isn’t being phased out like the less secure SMS 2FA, so it’s really not the end of the world here. The chance of permanent lockout is avoided, even if the whole Google Prompt system is still wack.
The SMS vulnerability is not because of your apps. It’s because of the LTE protocol itself. It can be intercepted or redirected without touching your phone.
