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.
- Enter your campus username and password. This is the same information you use to log in to the campus portal.
- Place a checkmark next to I'm not a robot.
- Click Login.
4. Click My Settings & Devices.
You do not need to choose an authentication method on this screen, however you will need to do it on the next screen.
5. Click Call Me, Enter a Passcode, Send me a Push, or If you don't have access to any of these options, select "I don't have access to my device. Get one-time authentication code"
Duo will call, text, send a push notification, or email you a code.
- Click Call Me and you will receive a phone call from Duo with instructions on how to authenticate (normally just press a number on your phone's dial pad).
- Click Enter a Passcode to get a text with a verification code. (Continue to 5.2)
- Click Send me a Push to get a push notification from the Duo Mobile app.
- Don't have access to your default device? Click I don't have access to my device. Get one-time authentication code. (Continue to 5.1)
Warning: If you chose option "D" Make sure you follow step 5.1 to prevent you from "looping" through the instructions.
5.1. Option D: I don't have access to my device. Get one-time authentication code.
- After selecting Option D; Fill out your personal information
- Click "Submit"
- Note: A code was sent to you personal alternate email.
- Select "Continue to Add device"
Important: You will be returned to the Duo Screen
- Make sure you select "My Settings & Devices" again.
- Click "Enter a Passcode" and enter the code sent to your email.
- Continue to Step 6.
5.2. Option B: After clicking Enter a Passcode, click Text me new codes. Then enter the code and click Log In.
- Click Text me new codes.
- Enter the code you receive in the verification code field.
- Then click Log In.
6. Click on Device Options next to your mobile device.
7. Click Activate Duo Mobile.
8. Choose the type of device from the list and click Continue.
9. Click I have Duo Mobile Installed.
10. You will see a QR code that you will scan with the Duo Mobile app on your device.
Prefer an email? Click Email me an activation link instead.
11. Open the Duo Mobile app on your device. Tap either Add Account or the plus sign icon at the top.
- Tap Add Account.
- Or tap the plus sign icon at the top right.
12. Tap OK to allow Duo Mobile to access the camera if prompted.
13. Hold your device up to the laptop/computer screen to scan the QR code.
14. Duo is now connected to your mobile device.
Notice that another way you can use your mobile device with Duo is to generate a passcode.
15. On your computer/laptop, click Continue to save your changes.
16. You're done! When you are prompted to authenticate with Duo, you can now choose to receive a push notification to this device.
17. Want to automatically receive a Duo push? Click on the When I log in drop-down menu and select Automatically send this device a Duo Push. Then click Save.
You will still have the option of authenticating with another device; this feature simply makes the process faster if you usually use the same device to authenticate.
- Click on the When I log in drop-down menu.
- Select Automatically send this device a Duo Push.
- Then click Save.
