Adding a Device to Your Duo Account

Important:  UIS highly recommends that you add multiple devices (at least 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. You can register a mobile phone, tablet, and even the phone of a trusted friend. (A trusted friend is a person you can reach out to if you ever need help getting into your Georgetown account [e.g., you forget your mobile device and can’t get into your Georgetown Google Apps account]. NoteThe trusted friend must also be enrolled in Georgetown Duo before you can add that person’s device.) 

Note:  You must first be enrolled in Georgetown Duo before you can add a device. Also, make sure you’ve installed the Duo Mobile app on your device.
