To maintain secure access to university accounts, Duo is requiring all users to update their Duo Mobile apps to version 4.85.0 or higher by March 31, 2026. (Note: Software versions count whole numbers. Version 4.106.0 is newer than 4.85.0 -- think "106" vs "85," not decimals.)
We encourage all UC Santa Barbara students, faculty and staff to update Duo Mobile to the latest version to benefit from the improved experience and enhanced security features. Please check your device's app store for the latest version of the app.
Note: The Duo Mobile app does not support older versions of certain operating systems and some country locations. Please refer to the following links for a list of supported Mobile OS, country restrictions, and other known issues:
