Switch to the Duo Mobile app: Texts, callbacks to be discontinued Feb. 24

To comply with new requirements from the University of California Office of the President, effective February 24, 2025, text messages and phone callbacks will no longer be available as login approval options for Duo, the multi-factor authentication tool used at UC Davis Health and UC Davis. These methods are less secure because they can be intercepted or exploited through phishing and SIM-swapping attacks. The most secure method is Duo Push, which provides real-time authentication and better protects against cyber threats. We are working closely with the UC Davis campus to implement these security improvements.

If you are already using Duo Mobile push notifications, no action is needed. If you have a new smart device and need to enroll or re-enroll in Duo Mobile, please access the campus and health sites here.

Alternative Options:

• If you do not have access to a smartphone or smart device, you may request a hardware token.
• If you have a long-term business need to continue using SMS or phone callback features, you may request a Cyber Safety Exception for approval.

For questions, please contact the UC Davis Health Technology Operations Center IT support 24 hours a day, 7 days a week at 916-734-HELP (4357).

Thank you for your cooperation in keeping our UC systems safe and secure.
