When setting up Google Authenticator for One Time Passcodes, you are also given a seed which can be used to resteup the app from another device.


Provided you don't lose that seed. If I end up homeless will lose all my stuff and limited to library access. You have to plan for the worst case scenarios with 2FA when things go bad.


Well at a certain point getting locked out stops being 2FA's fault and is simply due to the user's lack of responsibility.
