Setting up a security key for Duo authentication ensures a higher level of protection for your online accounts. This guide walks you through the process step by step, helping you seamlessly integrate this secure method into your two-factor authentication system.
Compatibility Notice
To ensure compatibility, please use the current version of Google Chrome, Firefox, Safari, or Microsoft Edge. Legacy devices that are incapable of receiving browser updates will be unable to authenticate via security key. To ensure that you can still authenticate to these legacy devices and to other potentially incompatible applications, we ask that you keep Duo Push active as a secondary authentication method.

All FDU-issued laptops are equipped with USB-C connections. If your device does not have a USB-C port, you can use a USB-C to USB-A adapter to connect the security key.
