## What Is MFA? | Multi-Factor Authentication
What Is MFA? MFA (Multi-Factor Authentication) an authentication method requiring users to provide two or more verification factors to access a resource. MFA combines something you know, something you have, and/or something you are.

## Why This Matters for Your Business
Without MFA, a single stolen password gives attackers full access to email, financial systems, and client data. For businesses handling sensitive information, MFA is often the simplest and most effective security measure available — blocking 99.9% of automated account compromise attacks.
