Duo Enrollment Multi-Factor Authentication Coming to College of Engineering

What is Duo and why do I need it?

Duo is a multi-factor authentication system for all UC Davis Central Authentication Service (CAS) protected sites and email services.

Duo enrollment requires users to use a second device to authenticate user logins. This secondary device should be something users have with them all the time such as a work or personal mobile device. You will use this second device to approve your logins after entering your LoginID and passphrase on your computer.

What happens if I do not enroll in Duo?

You will be unable to access UC Davis CAS-protected sites. This includes UCPath (earnings statements, tax withholdings, W-2s, etc.), email and more. Duo enrollment is mandatory for all UC Davis employees, per a November 2018 letter from Provost and Executive Vice Chancellor, Ralph Hexter. Note, the deadlines in this letter have been pushed back slightly due to campus closures during the fall quarter.

When do I have to enroll in Duo?

All UC Davis employees need to be enrolled in Duo by the time UCPath launches in March 2019. UCPath is a CAS-protected website that will replace the University of California’s At Your Service Online.

How do I enroll in Duo?

Before you enroll in Duo, you need to confirm you have the most up-to-date email client software:

Microsoft Office


  • Outlook Web
  • DavisMail
  • Outlook 2016


TIP: To confirm your Outlook product information on a PC, from the upper left-hand corner, click File→Office Account →Product Information. On a Mac, from the upper left-hand corner, click OutlookAbout Outlook

If you are not using Outlook or DavisMail, the College of Engineering IT Team will work with you directly to enroll in Duo. Do not proceed.

Next, please ensure your work or personal mobile device are up-to-date with the most current operating software.
