What is Changing?
In response to an increase in phishing attacks via text, OIT has begun to disable phone-based authentication (Text & Call). Staff, Faculty, Affiliate, & Service Accounts have already had these authentication methods disabled during the Fall 2025 semester. Due to the amount of Student and Alumni accounts, we will disable phone-based authentication throughout the Spring 2026 semester in groups, starting on Tuesday, February 17th.
How can I prepare?
If you have the Duo Mobile app installed on your device and use it as your primary authentication method, you do not need to change your 2FA settings.
If you primarily utilize phone-based authentication methods (Text & Call), you must install the Duo Mobile app on a supported device and enroll your device. Alternatively, you can open a ticket with the Information Security Team to discuss options if you do not have a device that supports the Duo Mobile app.
Note: It is recommended that you check your 2FA devices and remove any unused or outdated devices to strengthen your account further and clear out digital clutter.
