DUO: Adding and Removing Devices

Instructions on how to Enroll (Add), Remove and Change names for Duo devices.

Enroll a New Device

To start enrolling a new device, click Add a new device. If you don't see this link then your organization may not have enabled this functionality. Contact your Duo administrator to have a new device added.

Add New Device

Choose an authentication method and complete two-factor authentication to begin adding your new device.

If you're adding a new device to replace one that you previously activated for Duo Push, don't select the Duo Push authentication method on this page unless you still have the original device. If you don't have the original device, but you have a new device with the same phone number, then you can authenticate with Call Me or Enter a Passcode (SMS).

You can't add a new device from this page if you do not have access to any of your previously enrolled authentication devices; you'll need to contact your Duo administrator for help.


Add New Device


Proceed with the device enrollment process as shown in the initial Enrollment Guide. As an example, let's add another phone.


Device Type


Enter and confirm the second phone's number.


Enter Phone Number


Select the new phone's operating system.


Phone Operating System


Install Duo Mobile on the new phone and scan the QR code to activate.


Scan QR Code


The new phone is added and listed with your other enrolled devices. You can click Add another device to start the enrollment process again and add another authenticator.


If you want to continue using your original device with Duo, you can specify which of your devices you would like to be the default. Click the Default Device: drop-down menu and pick your default device for authentication. Click Save if you're done making changes.


Default Device


If this is the device you'll use most often with Duo then you may want to enable automatic push requests by changing the When I log in: option and changing the setting from "Ask me to choose an authentication method" to "Automatically send this device a Duo Push" or "Automatically call this device" and click Save. With one of the automatic options enabled Duo automatically sends an authentication request via push notification to the Duo Mobile app on your smartphone or a phone call to your device (depending on your selection).


Log In Options


Configure Device Options


Click the Device Options button next to any of your enrolled devices to view the actions available for that type of device.


Device Options


You can Reactivate Duo Mobile for an enrolled smartphone, Change Device Name for any type of phone, or delete any authentication device.


Configure Device


Change Device Name

Clicking Change Device Name will open up an interface to change the display name of your phone (hardware tokens can't be renamed). Type in the new name and click Save.


Change Device Name


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.


Device Name Changed


Remove a Device

If your new device is replacing the one you previously enrolled, you can remove the device you won't be using any more for authentication. Click the Device Options button next to the device you want to remove, and then click the trash can button to delete that device.

Remove Device


You'll have the chance to confirm that you want to delete that device.
