Two-Factor Authentication, Operating System Update

DUO multi-factor authentication service has been a critical tool in reinforcing the security of the university's data. This service will soon undergo operating system adjustments. Effective Dec. 1, 2020, Duo security will end support of the mobile app for iOS 11 and Android 7. While Push notifications and Duo mobile-generated passcodes will continue to work on already-installed versions of the app, we ask that you download the latest version of your device's operating system by Dec. 1 to avoid any service interruptions.

Beginning Feb. 1, 2021, all devices running iOS 11, Android 7, or older will no longer be able to install Duo Mobile from the Apple App Store or the Google Play Store. Therefore, it is imperative that you update your devices to their most current operating system to ensure continued access to Duo Mobile.

This end of support milestone means that:

Duo teams will no longer be able to troubleshoot issues with Duo Mobile on iOS 11 or Android 7 or older.
Duo Push will continue to work on already-installed versions of Duo Mobile on iOS 11 or Android 7, and users will continue to be able to authenticate.
Duo Mobile-generated passcodes will also continue to work on already-installed versions of the app, and users will continue to be able to authenticate.
SMS-delivered passcodes and phone callback authentication are not affected by this change. These methods do not rely on Duo Mobile.
Duo Mobile will continue to be fully supported on iOS 12 or Android 8 or newer.

We recommend that users upgrade to the latest iOS or Android version to receive these benefits. Beginning February 1, 2021, devices running iOS 11 or Android 7 or older will no longer be able to install Duo Mobile from the Apple App Store or the Google Play Store. Users who have already downloaded the app on iOS 11 or Android 7 or older devices will continue to be able to authenticate using the app.

Duo Mobile will continue to be fully supported on iOS 12 or Android 8 or newer, so if your devices are already operating on those up-to-date systems, no further action is required. If you have inquiries regarding this operating system shift, please contact infosec@asu.edu or call the Experience Center.
