Duo Universal Prompt

Princeton uses the Duo Universal prompt as a second layer of security for your Princeton account.  Duo verifies your identity using a second factor (like your phone or other mobile device).  This prevents anyone but you from logging in, even if they know your password. See the Duo Universal Prompt (external link) for more information and instructions.

When you log in to a Princeton application for the first time, the Duo enrollment process will start automatically.  When setting up Duo, it is best to perform this process on a computer or laptop, and have your intended mobile device with you.  We recommend installing the Duo Mobile app on your mobile phone for the best experience.  

1. From a computer, log in to a Princeton application e.g. Path to Princeton, your Princeton email or TigerHub.  
   The Duo Enrollment process will start and you will be guided through the setup process.
2. When prompted, select the Recommended methods for verification.
3. Download the Duo app to your device.
4. Activate Duo on your device.

The Duo Universal Prompt can now be used to manage and enable Duo devices instead of the existing Princeton Duo Portal. The Princeton Duo Portal will be retired during the summer of 2022.

Troubleshooting General

Solve Duo Common Issues (external site)

iPhone Troubleshooting

You are "Stuck" on Duo Window after Clicking Approve

Issue: After you click Approve, Duo does not take them to the Trust Browser screen (like it used to in old Duo).  To the user Duo push will appear to "get hung up" and not connect to the application. 

Suspected Cause:  The Trust Browser window is not automatically opening as it should.  We are seeing this issue with the TigerSafe app.

Resolution Option 1: Swipe Up

1. Swipe up from the bottom of your screen to view the open windows and applications on your iPhone.
2. You should see a Trust Browser window. 
3. Press Trust Browser.  Once you do this, you will not have to perform this step again for 90 days.
4. Swipe up again, and find the application window, for example the COVID Testing Kit window.

Resolution Option 2: Type the URL into a Browser

Instead of using an application on your phone, use your browser to navigate directly to the application. 

For example if you are having issues with TigerSafe, navigate to your browser and type in the direct URL:

• Covid test kit: go to https://scantestkit.princeton.edu
• Daily Symptom Check: go to https://tinyurl.com/PrincetonSymptomCheckApp

iPhone Focus (Do Not Disturb) Turned On

Confirm if you have "Focus" turned on, specifically, Do Not Disturb.  Do Not Disturb BLOCKS Duo notifications. Turn off Do Not Disturb.

Unexpected Duo Notification

If you receive a Duo push or phone notification that you did not expect or initiate, tap Deny.  DO NOT Approve. Tap Deny and immediately Contact Us. An unexpected Duo prompt could be a hacking or ransomware attempt.
