NOTE: Starting December 2, 2025, the phone call back method for Duo, the university’s multi-factor authentication tool, will change. Instead of being able to press any key to log in, users will need to press 1 to log in and will be able to press 6 to report fraud. After the change, you will need to listen carefully to the voice prompt instructions when you receive a Duo authentication request via phone call and press the appropriate key to respond.
After logging into a campus system or service through the Central Authentication Service (CAS), the Multi-factor Authentication (MFA) prompt will be displayed. Call Me will be offered as a possible authentication method.
The Call Me option allows you to use a mobile or landline telephone number as a second form of authentication. If selected, this option will dial a number connected to your iOS or Android device, or to a landline/phone number that is registered.
To learn how to add a phone number for callback to your Multi-factor Authentication Profile, view the Enroll a Phone Number in Callback article.
To complete MFA using the Call Me option, follow the steps below.
- Log into CAS. Under Choose an authentication method, click Call Me.

- Welcome to Duo. If you were not expecting this call, please press 6 to report fraud. Otherwise, press 1 on your phone to log in.
