Multi-Factor Authentication (Duo)

By December 9 2020, all students, faculty and staff are required to be enrolled in MFA. Get set up today!

Cal Poly uses the Duo multi-factor authentication (MFA) app to verify the identities of students, faculty and staff when they log-in to Virtual Computer Labs (AppStream)Common Management System (CMS), Virtual Private Network (VPN) and LastPass. Duo authenticates users' identities in two ways—with something they know (username and password) and something they have (mobile device or telephone). MFA, also referred to as two-step verification, or two-factor authentication (2FA), protects sensitive information by strengthening the security of the login process. At the end of fall quarter 2020, MFA will be required for all web-based services where Cal Poly credentials are used to log-in, including the My Cal Poly Portal and Email and Calendar (Office 365).
