Multi-Factor Authentication

What is Multi-Factor Authentication?

Multi-factor authentication (MFA) is a security measure that adds a layer of protection to sensitive information. It requires individuals to provide secondary information that verifies that they can access the information before viewing or changing it. 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 components should use multi-factor authentication through our security partner, Duo, to protect their identity and valuable personal information from cyber threats.
