Update Your Phone OS and Duo Mobile App to Avoid Authentication Issues

Summary: Duo is enforcing updated requirements. To avoid authentication issues, make sure your phone’s operating system (iOS/Android) and the Duo Mobile app are up to date.

Who this is for

• Employees who use Duo Mobile for Multi-Factor Authentication (MFA)
• Anyone receiving a notice that their phone OS or Duo Mobile app is out of date

What you need to do

1. Update your phone’s operating system (OS) (iOS or Android).
2. Update the Duo Mobile app from your device’s app store.
3. If you use Duo on a tablet or secondary device, update that device too.

Step 1: Update your phone OS

iPhone / iPad (iOS / iPadOS)

• Follow Apple’s steps to update iOS/iPadOS: Update your iPhone or iPad (Apple Support)

Android

• Follow Google’s steps to check for and install Android system updates: Check & update your Android version (Google Support)

Step 2: Update the Duo Mobile app

iPhone / iPad (App Store)

• Update Duo Mobile via the App Store (or enable automatic updates): Update apps on iPhone (Apple Support)

Android (Google Play Store)

• Update Duo Mobile via the Google Play Store (or enable automatic updates): How to update apps on Android (Google Support)

If you can’t update

• If your phone cannot be updated to a supported OS version, you may need to upgrade your device.
• In some cases, you may still be able to authenticate using SMS passcodes or phone call (these methods do not rely on the Duo Mobile app). Contact IT Services for help determining the best option.
