Note: The instructions below assume you have another device - such as a security key - or that you still have access to your old Duo Mobile device. If you only had one Duo Mobile device and lost access to it, you will need to call your IT support team or the Service Desk at 541-737-8787. You may also visit in person at Milne Computer Center room 201 during open hours to obtain a temporary Duo bypass code before following these steps. It's not possible to verify your identity via email, so a phone call or in-person visit are required for a bypass code.
The web browser steps are easiest to complete with a computer rather than a mobile device.
