As part of our ongoing efforts to protect UCSF from cybersecurity risks, on Monday, May 12, 2025, phone call (callback) and SMS text will no longer be available for Duo multi-factor authentication (MFA).  

This means that if you use these methods to authenticate to UCSF systems you must transition to one of the approved multi-factor authentication methods in Duo:

• Duo Push
• Duo Passcode
• Token

NOTE: If you are already using the Duo mobile app, this change will not apply to you.

To ensure you can use Duo MFA to authenticate and access UCSF resources, you will need to have the Duo mobile application installed to an iOS or Android smartphone. If you do not already have the Duo mobile app, please follow these instructions:

• Download and install the Duo mobile app, Version 4.55.0 or later
• Ensure your smartphone operating system is:
  • iOS: Version 14 or later
  • Android: Version 12 or later

Alternatively, if you do not have currently have a smartphone, you can request a token to authenticate to UCSF systems. Tokens are easy to use and will provide you with a passcode to enter for verification. See these token usage instructions.
