Multi-Factor Authentication

DUO MFAMultiFactor Authentication (MFA) is a two-step process that requires both a password and a second verification using a smartphone or a small token device that you carry with you. The University of California is adopting an MFA product called “Duo” and most UC campuses now require it to access institutional resources or soon will.

The campus is expected to transition to DUO MFA by October 15, 2019.
