The IAL guidelines require a rigorous identity proofing process, typically consisting of an on-site attendance event with superior strength evidence validation requiring the presence of a CSP representative.

NIST updates reflect an unmistakable shift toward prioritizing stronger, phishing-resistant authentication protocols, with email one-time passwords being deprecated and SMS authentication being downgraded accordingly.

IAL3 Identity Proofing

NIST's Identity Assurance Levels offer companies standards they can follow to verify the strength of an individual's digital identity claim. These three levels - IAL, AAL and FAL - determine the degree of certainty between an individual's digital and real identities, protecting both parties against impersonation or fraud.

Traditional IAL3 requires in-person attended verification by a proofing agent or remote verification using special hardware. These methods offer greater deterrence against social engineering and phishing attacks by combining document validation with biometric comparison to ensure that any claimed identity matches up with its real counterpart in reality.

Mitek's unified, integrated solution provides IAL3-level authentication by combining document authentication, live image capture and biometrics into one cost-effective yet user-friendly process - making it the ideal option for organizations looking to expand digital authentication processes.

NIST 800-63A

NIST 800-63A IAL3 is an essential digital identity management guideline that establishes how organizations should verify identities, authenticate users and exchange authentication data safely. It serves as an indispensable framework that facilitates phishing-resistant multifactor authentication (MFA), passwordless authentication (PA) and secure federated identity practices.

The 2025 revision of NIST SP 800-63-3 marks a dramatic shift away from checklist-based requirements towards risk-based Digital Identity Risk Management (DIRM) framework that emphasizes resilient authentication mechanisms. A key objective here is preventing impersonation by attackers in phishing attacks.

The revised guidelines also rename the levels of assurance from Identity Assurance Level (IAL) to AAL (Authentication Assurance Level) and FAL (Federated Assurance Level), highlighting the significance of selecting the most suitable level of verification based on risk profile and user populations, to avoid over- or under-verification. HYPR's robust, FIDO Certified and NIST compliant authentication solutions directly support organizations meeting updated guidelines by offering high IAL3 levels of identification proofing.

IAL3 Compliant Solution

Identity verification aims to confirm that claimed identities match with actual people in real life. It's crucial that identities are properly authenticated for many applications such as financial services, healthcare services or sensitive personal data access. Frameworks like NIST SP 800-63 have established assurance levels (IALs) which standardize confidence levels that organizations have in an individual during authentication processes.

IAL 1: Minimal identity proofing, usually relying on self-asserted information without rigorous validation processes. IAL 2: Requires formal proofing methods such as verified documents and verifying identity attributes. IAL 3: Demands stringent in-person or supervised identity verification processes with multiple identity documents and biometric verification processes as well as chain of custody policies, anti-spoofing protection measures, and detailed auditing processes incorporated.
