Multi-Factor Authentication (MFA) helps verify that the person signing in is authorized to access 91ɬ�� systems. MFA adds an extra layer of protection by reducing the risk of unauthorized access.

MFA requires more than one form of verification when signing in and helps protect university systems, applications, and data across the 91ɬ�� environment.

Access the M91ɬ�� portal at  to initiate the MFA enrollment. Refer to the MFA Enrollment Instructions for a step-by-step guide to the enrollment process.
