2-Factor Authentication: Setting Up a New Phone

If you get a new phone and had either the Google Authenticator app or the DUO Mobile app on your old phone, you will need to follow these instructions in order to get those apps working on the new phone:

  • If you did not have these apps on your old phone and were just receiving the 2-factor verification codes as a text, then you do not need to follow these directions.
  • If your phone number did not change for your new phone, you do not need to do anything in order for you to receive verification codes as a text. If your phone number did change with your new phone, please contact the help desk for further instructions on setting it up for 2-factor authentication.
