The DUO Two-Factor Authentication upgrade was deployed on November 20, 2023, to enhance and secure WashU systems and applications access. A smartphone or tablet with the Duo Mobile app installed is required to use this new and preferred verified push method of multi-factor authentication. There are circumstances where you might not be able to download the latest DUO application. For instance, older phones may not support the app for security and compatibility reasons, but the most recent versions of Android and Apple operating systems typically support the Duo mobile app. We recommend you keep your device’s operating system up to date to ensure compatibility with the Duo Mobile app and to take advantage of the latest security features. Here are guides on how to allow automatic updates on iPhone and Android:
- Update iOS on iPhone – Apple Support (ME)
- How to update the Play Store & apps on Android – Google Play Help
If you cannot download the Duo Mobile app on your phone or tablet, you may submit a Duo exception request with our office. For questions and help with Duo, refer to the WashU 2FA Frequently Asked Questions webpage or call the WashU IT Service Desk at 314-933-3333 for assistance.
