How to replace a phone in Duo

[ Back to Duo ]

If you run into any problems after following these instructions, email us at oit@uci.edu or give us a call at 949-824-2222. For your security, we'll need to speak with you to verify your identity before we can assist.

Before you start these instructions, make sure the DUO Mobile app is installed on your phone (search "Duo Mobile" in the Apple or Android app store).

Step 1: Register Duo on a new phone

Click on the blue button below to open the Replace Phone page in the Duo Support Desk web application. If prompted, sign in with your UCInetID and password. You may also use this URL:

https://duosupportdesk.service.uci.edu/replacePhone.htm

Select the radio button next to your telephone number and then select Submit. The system will send you a text message.

Step 2: Activate Duo on your phone

Check your mobile phone for a text message that looks like this, and tap on the link.

The link should open the Duo Mobile app on your phone (depending on your device, it might first open your web browser and ask if you want to open the Duo Mobile app). If it does, select Open. Please note that the link will expire in 30 minutes.

You're Done!

Your duo app should now be open, and display a passcode (as seen below). This means that you're finished, and will be able to use duo pushes and passcodes with your phone.
