Multifactor Authentication (MFA) Service

Yale has experienced a substantial increase in attempts to compromise NetIDs. The most common cause of compromise is email phishing. Scammers’ methods for gaining access to passwords have outpaced security measures, which potentially allow them to access our systems and data. This puts our intellectual property, faculty research data, and personal information at heightened risk. DUO Everywhere significantly reduces Yale’s security vulnerability and helps us to create a more secure Yale. 

What is DUO Everywhere? 

DUO Everywhere: Multifactor authentication (MFA) adds a second layer of security to cover both on- and off- campus for VPN connections, Microsoft Office 365 and CAS logins.

  • Once your NetID has been activated, setup your Duo device by clicking “DUO Everywhere” in the “Check Your DUO Everywhere Status” section. 
  • Follow the steps prompted to choose your device setup. It is recommended to set up a minimum of two devices.

What to Expect: 

What should I expect once I enroll in DUO Everywhere? 

DUO Everywhere will ask you to authenticate once per application or browser, per device. 

How long does DUO authentication last? 

When DUO requests authentication, there will be an option to extend the session for 90 days. Please be aware that you will need to do this for every session you authorize.
