Introduction
What is Multi-Factor Authentication (MFA)?
Office 365 MFA helps protect organizational data by preventing unauthorized access through phishing and other cyber threats. At Saint Cloud State University, MFA is required for Office 365 accounts to safeguard user data and the campus network.
Multi-Factor Authentication (MFA) is a security process that requires users to provide two or more verification methods to gain access to a system. These methods come from independent categories of credentials to confirm the user's identity. Common combinations include:
- Password validation
- Mobile device verification (via text message or authenticator app)
- Biometric identification (e.g., fingerprint, iris scan, or facial recognition)
A typical MFA setup involves entering your password and then confirming a code sent to your mobile device or approving a login request through an authenticator app. This layered approach significantly reduces the risk of unauthorized access.
Once enabled, users must verify their identity using an additional method beyond their username and password.
Why Use Multi-Factor Authentication?
MFA is widely adopted by businesses and institutions to enhance security beyond traditional passwords. It is especially recommended for protecting sensitive data such as:
- Primary email accounts
- Financial information
- Health records
Many organizations now require MFA as a standard security measure to access systems and services.
