Note: If you currently use the Duo Mobile App for 2FA when signing into your UC Merced account, you do not need to take action.
Beginning in Spring 2026, OIT will be disabling phone-based authentication methods (Text & Call) on Duo accounts to address ongoing security concerns with these methods. To learn more about when this will occur and what you will need to do, please visit our support page for more information and FAQs.
