DUO support for older model phones ends today

December 1, 2020

Effective December 1, 2020, Duo Security will end its support of the Duo Mobile application for iOS 11 and Android 7. Duo Mobile will continue to be fully supported on iOS 12 or Android 8 or newer. As of today:

  • Duo teams will no longer be able to troubleshoot issues with Duo Mobile on phones with iOS 11, Android 7, or older versions.
  • 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 continue to work on already-installed versions of the app, and users will continue to be able to authenticate.

The change does not affect SMS-delivered passcodes and phone callback authentication. These methods do not rely on Duo Mobile.

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.
