Additional Information

Duo Two-Factor Authentication is a security measure that requires users to provide two forms of authentication to access their accounts. This provides an extra layer of security beyond the traditional username and password, making it more difficult for unauthorized users to gain access to sensitive information. We recommend having at least two Duo options to help ensure your access in case of unexpected circumstances like lost internet, lost device, etc. 

If you have a replacement device and cannot authenticate with Duo using the previous device to access the Duo enrollment page, please contact the ITS Service Center for assistance. We will be able to help you add your replacement device.
