Multi-Factor Authentication is the single most impactful identity control available — CISA data shows that MFA prevents over 99% of account-takeover attacks — and phishing-resistant MFA using FIDO2/WebAuthn is now mandated by US Executive Order 14028, OMB M-22-09, and every major cyber insurance policy. Zero Trust architectures treat MFA not as a one-time login gate but as a continuous signal feeding step-up authentication decisions throughout a user session.
