Duo - Add A New Device
Using a browser or computer that you do not normally use (or clear your cache on your regular browser), go to the enrollment site and log in. Then click Add a new device.
Choose an authentication method and complete two-factor authentication to begin adding your new device as shown in the initial enrollment guide.
Note: If you do select Touch ID, you will not be able to use this option with Respondus Lockdown browser.
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 a phone call or SMS passcode.
If your new device does not have the same phone number as your original device; you'll need to contact the Service Desk for help.
