Students: Setting Up Duo Mobile App on Your Mobile Device

This article covers how students can set up the Duo app on their mobile device to receive push notifications to authenticate with Duo two-factor authentication.

These instructions show setting up an Apple iPhone, but the instructions are similar for other devices.

1. Download and install the Duo Mobile app from the Apple App Store or Google Play Store on your mobile device.

2. Open a web browser on a computer or laptop to the Student Duo Setup site.

You will need to take a picture of a QR code with your mobile device as part of this process, so you can't use your mobile device to access the Student Duo Setup app.

Open your web browser to the Student Duo Setup app.

3. Enter your campus username and password. Check the I'm not a robot box. Then click Login.
