Summary: 

The Duo Mobile app must be updated to version 4.85.0 or above (the most current version is 4.107).

Details:

UCSF IT has identified about 1,600 users who require an update to the Duo Mobile application used to authenticate securely with their UCSF accounts and another 300 users who must upgrade their operating system or device to install the latest version of Duo Mobile.  

To maintain seamless operation of the Duo Mobile app, users are asked to update their devices by Tuesday, March 31.  

What's happening 

Effective Feb. 3, a Duo Mobile app pop-up began displaying a warning regarding the need to update. If not updated, on March 31, the app will cease functioning properly. Multifactor authentication (MFA) will be unavailable, and some UCSF resources may become unavailable, including VPN and off-network access to email. To prevent this from happening, update the Duo Mobile app to version 4.85.0 or above (the most current version is 4.107).

Action required 

Make sure your Duo mobile application is updated to version 4.85.0 or above (the most current version is 4.107). In some cases, this may require you to update your mobile device to iOS 17 or later or Android 12 or later depending on your device type.

Need to upgrade your device? 

If you are unable to install either iOS 17 or Android 12 on your device, you will need to obtain a new device that is compatible with one of them in order to continue using Duo. If obtaining a new device before March 31 is not feasible, or if you would prefer not to use a mobile device for Duo authentication going forward, you can alternatively request a Duo hardware token.
