Important announcement about using Yale's MFA when traveling:
You must DUO-authenticate to access any CAS-protected or VPN-protected application from off-campus. This includes Microsoft Office 365 (e.g Outlook, Teams, OneDrive).
As of March 2022, DUO is blocking access to its services from sanctioned countries. These countries are regularly updated and explained on DUO's Knowledge Article. If you are traveling to an affected country, you will be unable to access most of Yale's online services.
Please see the University statement on Yale's U.S. Sanction and Embargo programs for more details.
