How to Add a YubiKey to Your Duo MFA Account

YubiKeys are consumer purchased hardware tokens that can be linked to your Duo account to allow Multi-Factor Authentication (MFA) to Northwestern account. 

1. On your computer, navigate to any page that prompts you to login via Duo MFA (i.e. CAESAR for students, myHR for faculty/staff).
   NOTE: If you are already logged in, you will need to use a new browser or a private browser window to trigger the Duo MFA login page
2. Click on Other options.
   
    
3. Click on Manage devices 
   
4. Verify your identity through one of your available options to manage your Duo devices.
   NOTE: Step 3 and Step 4 seem almost identical, but are necessary to get to Manage devices in Duo. Step 4 is asking you to verify your identity through Duo before it will allow you to see, add, or manage any of your Duo devices. If you do not have an active Duo verification option, contact the IT Service Desk.
   
5. After you have confirmed this is your account via Duo login, you will be given the option to add a device.
