Product: MacOS TouchID with Duo MFA
Audience: Staff with MacBooks

Overview

MacBooks have a fingerprint scanner that can be used as an authentication option with Duo. It stopped working for users who upgraded to SequioaOS. This is a walkthrough to set up Touch ID for Duo for the first time on a new device.

For general instructions on Duo usage, refer to the Duo Guide.
 

Add Touch ID (Fingerprint) on MacBook for Lockscreen and Autofill

• Go to System Settings > Touch ID & Password, then click “Add Fingerprint”
  • Follow prompts until your fingerprint is recorded on the MacBook
    
    

Log in to Duo Central

• Open Classlink found in your CSD Bookmarks, then click on the CSD Suite folder.
  
  
  
  
  • Next, click on Duo Central
    
    
     
• Sign in to your school email account. If the address isn’t correct, click the edit button and type out your full school email address and school email password.
  
  

Edit and/or Add Touch ID

• See screenshot. If it says “iCloud Keychain” instead of Chrome on Mac, click the Edit button and select Delete. Once deleted, click Add a device.
  
  
  • Troubleshooting: If you previously had this enabled on a different device, deleting the old Touch ID will help resolve looping issues.
     
• Once you’ve clicked Add a device, select Touch ID and then click “Your Chrome profile”, rather than ”iCloud Keychain".
   
  
  
   

You should now be able to use your MacBook Fingerprint reader for Duo authentication! The next time you sign into Duo for authentication, select other options and you’ll see Touch ID. 

• Select Touch ID and put your finger on the reader. You should be logged in, and Duo should use that as the primary method for authentication. Success!

Conclusion

You should now be able to use your Touch ID fingerprint scanner on a MacBook with Duo, even if you upgraded the OS to Sequioa and it had stopped working.
