Security certificate changes may disrupt MFA access for users running outdated Duo Mobile versions.

Duo recently announced a major security update that will impact all users relying on the Duo Mobile app for multi-factor authentication. On February 2, 2026, Duo will be updating its security certificates. Given this update, any device running an older version of the Duo Mobile app may eventually cease to function. More specifically, this may mean users cannot log in to university systems, nor any other services dependent on MFA, without attention to this new requirement well in advance of the deadline date.

The update is specifically to Android users running Android 11 and later, as well as iPhone or iPad users running iOS 15 and later. It is highly recommended that users verify their current Duo Mobile app version to determine if an update is required. The Duo Mobile app version can be verified by opening the Duo Mobile app, tapping the three-line menu in the upper-left corner, and looking at the version number at the bottom. Devices with version 4.85 or greater require no action; those below this threshold should be updated.

Updates to the app are straightforward: Open the App Store or Google Play Store, search for Duo Mobile, and install the latest update. If the store offers an “Open” option, the app is already current. For devices running older versions of Android, Duo has provided special versions for Android 8, Android 9, and Android 10, and for those, installation instructions are available from Duo’s official knowledge base. Specifically excluded from the service are non-standard Android devices and all phones that have highly customized operating systems.

Duo strongly advocates for the use of Duo Push through the Duo Mobile application since it remains the most secure and convenient way to authenticate. The app provides end-to-end encryption, works on Wi-Fi or cellular data, provides contextual information on login location and application-specific details, thus helping users quickly identify and deny suspicious login attempts. Updating the app ensures that their application continues to provide access securely with no disruption.
