What Is MFA and Why Is It Important?

What Is MFA and Why Is It Important? is an important topic for anyone who uses a Windows PC or manages technology for a business. Understanding the basics can help you make better decisions about security, prevention, and ongoing IT management.

Key Points

• What Is MFA?: Multifactor authentication requires users to provide more than one type of authentication evidence, such as a password plus an authenticator app or security key.
• Why MFA Helps: Even if a password is stolen, an attacker may be unable to access an account without the additional authentication factor.
• Where to Use MFA: Enable MFA for email, cloud services, administrator accounts, remote access, financial systems, and other important accounts wherever supported.
• MFA Is Not a Complete Security Strategy: MFA should be combined with strong passwords, endpoint security, patching, monitoring, backups, and user education.
