NIST SP 800-63-4 modernizes digital identity through a modular framework of IAL, AAL and FAL standards. IAL standards emphasize antiphishing-resistant multifactor authentication (MFA) as well as device-bound syncable authenticators (such as FIDO Passkeys) to combat fraud and build trust within online services. Reaching IAL3 requires on-site attended identity proofing with document and biometric validation, direct supervision by a trained CSP representative, liveness detection capabilities to thwart more sophisticated attacks, as well as liveness detection to limit them.
