What is a Multi-Factor Authentication?

Definition

Security process requiring two or more verification factors (knowledge, possession, inherence) to access systems. MFA combines passwords with SMS codes, authenticator apps, biometrics, or hardware tokens to prevent unauthorized access even if passwords are compromised."

Why This Matters

Multi-factor authentication significantly strengthens security beyond passwords alone. MFA prevents unauthorized access even when passwords are compromised. MFA support is now considered essential security hygiene.
