MFA: Two-Digit Authentication Code is Hidden Behind the Authenticator App

University members who are attempting to log in to a University resource on their mobile device that requires Multi-Factor Authentication (MFA) and are using the mobile app verification method may experience an issue where the two-digit code becomes hidden by the Authenticator App.

  1. Look to see if you have the option to select I can't see the number (Figure 1). If so, you may select that option to see the number again and then tap once more to return to the Authenticator pop-up to enter the number in the field provided.
