**Starting February 24th, UC Davis Health & UC Davis Campus will no longer offer phone call or SMS/Text as a way to authenticate.**

Enroll your device to use 'PUSH' authentication now.

You must enroll in Health AND Campus accounts to have access to all our secured applications.

We recommend the easiest way with PUSH authentications. For accessibility needs, you may request a Duo hardware token for access: DUO Hardware Token - IT Self Service, or contact the Technical Operations Center: 4-HELP (916-734-4357).


DUO offers four different methods of authentication:

Push is used when Duo's mobile application sends a push notification to your smartphone. Just tap “Approve” to authenticate.

Passcode (softtoken) from Duo’s mobile application it provides a 6digit unique code to authenticate.

Token is the simple feature where Duo Security allows to manually enter a passcode via a Hardware Token.

SMS is when Duo Security sends a passcode to your device via a text message or SMS. You then authenticate by entering your onetime passcode.

In addition to your password, multi-factor authentication provides a second layer of security by sending an approval request to a pre-approved device. By requiring two different modes of authentication, UC Davis Health can protect user logins from remote hacks and phishing attacks that may exploit stolen user names and passwords.


The two modes of authentication include:

  1. Something you know: A unique username and password
  2. Something you have: A smartphone with an app to approve authentication requests
UC Davis has incorporated Duo Security as a multi-factor authentication solution.

Login credentials are increasingly easy to compromise. Over 90% of breaches today involve compromised usernames and passwords. Multi-factor authentication enhances the security of your account by sending an approval request to a secondary device you have (smartphone) to verify your identity. This step prevents anyone but you from accessing your account, even if they know your password.
Duo Security is a third-party vendor that provides a software service that utilizes multi-factor authentication to ensure secure access to UC Davis Health services and data.
There are a couple of reasons you could be getting invitations.
  1. There are two Duo systems, one for Campus applications and one for Health System applications. HS employees use both. You may be registered for one but not both.
  2. You may have more than one email address in our system.
If you have not registered in both systems, click the gold bubble above on the left for Campus or the gold bubble on the right for HS.
If you are certain you are enrolled in both systems, reply to the invitation you received and let us know you have enrolled.

There are several reasons you may not be receiving push notifications, please try the following troubleshooting steps.
  1. Check network connectivity on your enrolled device.
  2. Have the Duo application open when authenticating.
  3. Refresh the application, when attempting to authenticate:
    • With the Duo application open, hold and drag the top of the application downwards. This will refresh the page and display any pending notifications.
  4. Try using a different method of authentication. For example, try the passcode option.

Users are locked out when there are 5 consecutive failed login attempts.
  • Make sure the Duo Mobile application is open: A user lockout sometimes happens when the Duo Mobile application sends multiple attempts to authenticate that are not responded to. To reduce the number of unanswered push notifications, try opening the Duo application prior to sending the push request.
  • Authenticate to an enrolled and available device: Persistent attempts to authenticate to an inactive or incorrect device can cause a lockout. If you did not complete the enrollment process, multiple attempts to authenticate with Duo will cause a lockout.
