Use Yale's Multifactor Authentication (MFA) Service 

Click with Caution header

You must DUO-authenticate to access any CAS-protected or VPN-protected application from off-campus.

DUO Everywhere extends DUO authentication to Microsoft Office 365 (e.g. Outlook, Teams, OneDrive) and CAS logins on and off campus.
