Effective February 9, 2023, the Duo Mobile app will no longer support Android 8, Android 9, and iOS 13. At CSU, push notifications through the Duo Mobile app is our recommended primary method for two factor authentication. Two factor authentication is required for accessing university email accounts, the GlobalProtect VPN, and other CSU services. 

 

Duo Push and Duo Mobile-generated passcodes will continue to work on already-installed versions of Duo Mobile on Android 8, Android 9, and iOS 13, and users will continue to be able to authenticate. However, no support or troubleshooting will be provided if issues are encountered.  

 

We recommended users upgrade to the latest iOS or Android version. We also recommend users set up more than one device as a 2nd factor authentication method with Duo.
