Multi-factor Authentication (MFA)
Changes following the Fall 2025 Semester
As of December 18th, direct phone calls will no longer be an authentication option within UA Duo accounts. If you are using Duo's "Call me" function as your primary authentication, you are required to migrate to a new method of authentication, such as the Duo Mobile app. If you have any questions, please reach out to the Helpdesk.
Multi-factor Authentication (MFA) is required for all active students, faculty, and staff with a UA account. This system enhances the security of UA accounts using secondary account confirmation powered by Duo, using a tablet, mobile phone, or USB security key. Students may also use Device ID. This affects all systems within the UA Single Sign-on: UAOnline, Banner, UA Google, Blackboard, and Zoom. MFA settings are available in UAS ELMO on the Security Settings page, under Multi-Factor Authentication section. On first-time access to a service secured by Duo, users are prompted to set up their Duo profile.
Some best practices:
- Have MFA set up on a device you'll always have on hand.
- A personal device is not required. MFA can be configured to use a dedicated USB security key.
- Always have a backup. If you misplace your phone or USB key, you'll want a backup device to expedite removing lost items (Directions for adding backup devices).
- After changing or loss of any devices, update your Duo profile (Directions for Duo Mobile app)
- For students without a consistent security device, please contact the UAS Helpdesk for options.
