Duo - Manage Your Devices


When signing into a service protected by 2-factor authentication using Duo, the authentication prompt will display a Manage devices button. To manage your devices, select a device to use, choose an authentication method, or complete second factor authentication. You can't get in to the device management portal if you do not have access to any enrolled devices; then you'll need to contact your department's IT support office for assistance.

Device Management Portal

After authenticating, you'll see the device management portal. This is where you can edit your existing devices or add a new one.

Add Another Device

Click Enroll another device. You'll be walked through a few steps to get Duo Mobile installed and activated on your new device.

Activate Duo Mobile

Click Activate Duo Mobile in the actions dropdown to get an existing device setup to complete secondary authentication. After answering some questions about your device, you will receive a new QR code to scan from your mobile device which will complete the activation process.

Change Device Name

Click Change Device Name to open a window to change the display name of your phone. After successfully modifying your phone's name, not only will you see this from now on when managing devices, but it will also be how your phone is identified in the authentication drop-down.

Remove Device

The device manager also lets you remove your devices. If you are unable to delete a device, contact your department's IT support office to have it removed.

Note: You may not remove your last device. If you wish to remove it, first add another, then delete the original.

Set Default Device

If you authenticate with more than one device, you can specify which you would like to be the default. In the list of actions, click Set as Default and that device will be moved to the top of the list making it your default device for authentication.
