Update Your Settings

You can change and update your Duo options any time. See:

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'll need to install the Duo Mobile app on your new phone and reactivate the app.

Want to Change Your Default Device?

Your default device is the one Duo presents when you log in. To change the default, refer to Change Your Duo Options and Settings.

Remove Unneeded Devices and Phone Numbers

Remove phone numbers and devices that you no longer have or use from your Duo options. Refer to Change Your Duo Options and Settings 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.
