Everyone with a compatible mobile device should update to the new version of the Duo Mobile app (v4) when it becomes available in mid-October.

What's Changing

Duo Mobile v4 offers a new visual design (see above) with the Approve button on the right and the Deny button on the left. (This is the opposite location from the v3 app.)

What's Not Changing

The core functionality of Duo Mobile is not changing. You will continue to be able to:

  • Receive a Duo Push (NYU's recommended way to MFA)
  • Use passcodes
  • Add, edit, reorder, and remove accounts
  • Use dark mode
  • And anything else you can do in the current version of the app

How to Update the App

  • If auto-updates are enabled on a compatible device (iOS 13+ and Android 8+), your Duo Mobile app will automatically update to v4 sometime between October 11 and October 18, 2021
  • If you don’t have auto-updates enabled but your device is compatible, you should manually update to v4 on or after October 18, 2021 at the App Store (iOS) or Google Play (Android)
  • If your device's operating system isn't compatible with Duo Mobile v4, you won’t be able to upgrade to v4
    • v3 of the Duo Mobile app will continue to work with NYU Multi-Factor Authenication until Duo chooses to discontinue support at an as-yet-unannounced date
    • As soon as you upgrade your device to a compatible operating system (iOS 13+ or Android 8+), be sure to install Duo Mobile v4 at the App Store (iOS) or Google Play (Android) to avoid future MFA issues.  

Tip: Many services require recent operating systems to support cybersecurity and functionality. As a best practice, keep your devices and their operating systems up to date.
