MFA

Definition

Multi-Factor Authentication—requiring multiple proofs of identity to log in.

In Plain English

MFA is like needing both a key and a code to enter—even if someone steals your key, they cannot get in.

Real-World Example

After entering your password, you also enter a code from your phone to complete login.

Why It Matters for Your Work

MFA dramatically reduces account takeover, even if passwords are compromised.

Common Mistake

Using SMS-based MFA for high-security accounts. Authenticator apps are more secure.
