Duo Two-Factor Authentication
Two-factor authentication verifies your identity on a separate device (e.g., your smartphone) through a 3rd party application known as Duo.
Systems that require Duo include:
- VPN (remote.ucsf.edu)
- Outlook Web (email.ucsf.edu) when not at UCSF. Access from mobile email clients is not affected.
- Connect Portal - Beginning in May/June 2018 doctors and providers who use APeX Connect Portal will be required to use Duo upon logging in with their medical center account. Check back in the coming weeks for more information.
- ServiceNow - ETA June 2018
What is Duo?
Duo is a third-party application that UCSF uses for two-factor authentication. It requires second verification on another device (something you have with you, such as your smartphone) to authenticate your identity.
Duo provides several authentication options, but the most convenient is through the Duo Mobile smartphone app.
To download the app, click the appropriate link below for your smartphone:
Or search for “Duo Mobile” in your phone's app store.
How do I Enroll?
Check your inbox for an email titled "Duo Security Enrollment" from "[email protected]." Receipt of this email means you have been automatically enrolled and can simply follow the directions in the email.
To complete enrollment you will need a phone - either a mobile phone that can receive text messages, or a landline. As you proceed with the steps, you will then be prompted to enter your number to perform a one-time activation.
You are now enrolled in Duo!
If you did not receive this email please follow the instructions on our Duo Manual Enrollment page.
Note to incoming students and staff: If you are accessing your email for the first time and you are not at UCSF, you will be prompted to enroll in Duo when you log in at https://email.ucsf.edu. Follow the on-screen prompts to enroll. If you need assistance please contact the UCSF IT Service Desk.
Note to Zuckerberg San Francisco General staff: If you’re using ZSFG's WebConnect, the Duo app is already installed on your phone. You can use the same app for UCSF systems like VPN and Outlook Web.
