Per @Mhurd the user has a backup 16 digit alphanumeric scratch code that is used as an emergency back-up code for reset. This was not included in original log-in tasks/design.
Specifically we need:
- An affordance for 2FA users to let them enter a specialized code to reset their access
- If the user taps it, we need to present a secure text-box where they can enter their scratch code
- User should get feedback on success or failure
