Reactivate or Update Duo

You can change and update your Duo options any time. See Manage Your Duo Devices for instructions with screenshots.

If you replace a device or phone number and you don't have a backup option (such as an office landline) enrolled in Duo, you may be unable to log in to update your settings. No worries. You can call the ITS Service Center for a bypass code to let you in.

Got a New Smartphone?

If you replace your smartphone with a new one but keep the same phone number, you may need to install the Duo Mobile app on your new phone and reactivate the app.

  • Refer to Manage Your Duo Devices for the detailed steps.
  • Before you sell or give away your old device, back it up and then erase all content and settings.

Got a New Phone Number?

Switching to the App?

Remove Unneeded Devices and Phone Numbers

Remove phone numbers and devices that you no longer have or use from your Duo options. Refer to Manage Your Duo Devices for the detailed steps.

Report lost or stolen devices! If you used a lost or stolen device to access or maintain sensitive university data, report the theft or loss, and ask to have the device deleted from your Duo options if you are unable to do that yourself. See Report an IT Security Incident.
