Adding a Device to Your Duo Account for Account Recovery

IMPORTANT:  It is mandatory to add a secondary device to your Georgetown Duo account. By having more than one device registered, you will still be able to log in to your applications (by switching to that device during the Duo authentication process), even if you forget, damage, or lose the device, such as your mobile phone, you use regularly to authenticate.
