Multi-Factor Authentication (MFA)

Multi-factor authentication (MFA) is a security measure that adds an additional layer of protection to sensitive information. It requires an individual to provide secondary information that verifies that the individual is authorized to access the information before the individual is allowed to view or change the information. For example, an ATM requires you to have both your physical bank card and your four-digit pin to get cash—multiple factors.

All faculty and staff from UNT System Administration and all UNT System institutions should use multi-factor authentication (MFA) through our security partner, DUO, to protect their identity and valuable personal information from cyber threats.
