Description
Duo no longer supports older versions of the app (below 4.85) and will eventually block them from accessing ISU systems. To prevent login issues, update your Duo Mobile app to version 4.85 or above.
- Note: If you’re already using version 4.105.0, the current version, no action is needed.
