Yubico Passkey

This article will show you how to add a Yubico passkey as MFA. This will be used when a user does not want to install Microsoft Authenticator on their device.

1. Install Yubico Authenticator on your machine for the initial setup of the Yubico Key. This can be done through Action1.
   
   
2. Plug the Yubikey into a USB slot. It will be recognised in the program. Select "Factory Reset" on the right-hand side.
   

   
   

   
   
3. Select "FIDO2" and reset, follow the prompts, then close once done. This is done, so when it is initially setup for a user, they can create their own pin code.
   

   
   

   
   
4. Navigate to Entra and find the user. On the left hand side select "Authentication methods". Then "add authentication method".
   

   
   
   

5. Select "temporary access pass". This is needed because a source of MFA is needed before adding a passkey.
   

   
   

   
   
6. Once added, note the code.
   

   
   

   
   
7. Now head to the usersUSERS online microsoft acocunt,acocunt (office.com), head to security info. Add a sign in method "Security Key".

9. Select "USB Device" and follow the prompts.
   

   
   

   
   
10. As long as the Yubikey was factory reset, you will be prompted to create a pin. Follow the prompts.
    

    

    
    
11. Name the key, YubiKey will do fine.
    

    
    

    
    
12. A hardware passkey has now been setup. Temporary access pass (TAP) duration is usually 1 hour, once time has run out, passkey will still be usable.
