Duo provides an extra layer of security to protect your accounts and your data. 

If hackers steal your ID and passphrase, they still can't access your account, because they won't have the verification from Duo. For more about Duo at UC Davis, see https://movetoduo.ucdavis.edu. Note to applicants for admission to UC Davis: You can enroll in Duo at UC Davis once you are accepted and file your statement of intent to register.

To enroll in Duo at UC Davis, follow the below steps:

Step 1: Select a device to enroll in Duo, and enroll that device

You enroll by registering the primary device you will use to login to your accounts. Select the device from the list below, then follow its corresponding link for instructions on how to enroll in Duo with that device. If you're not sure which devices to enroll, read this article.

Step 2: Register a second device in Duo

Registering a second device gives you a backup method of authenticating with Duo when your primary method is not available. Follow these instructions to register your second device.

Step 3: Use Duo

Once you have enrolled in Duo, you can select your preferred authentication method. Supported methods include Duo push, Duo mobile passcode, and Bypass code. After that, each time you log into a Duo-protected site, Duo will use your chosen method to authenticate your login.

• • If you are prompted to enter a verification code when authentication with a Duo push, this is likely because of Risk Based Authentication. See KB10464 for additional details.
