Unlock full Trustswiftly nist 800-63-4 ial3 compliance with a modern identity platform, designed specifically around user needs. Continuous verification eliminates password resets altogether.
HYPR’s NIST 800-63-4 IAL3 solutions support remote, supervised identity proofing sessions using chat, video, facial recognition and liveness detection to reduce cyber liability insurance premiums and password reset costs.
Verification
NIST Digital Identity Guidelines provide a core framework for digital identity management that encompasses verification, authentication and federated identity management. Their latest version seeks to combat identity theft and fraud by strengthening measures to verify users’ real identities while promoting robust phishing-resistant authentication protocols. Furthermore, separate assurance levels exist between proofing, authentication and federation to enable adaptable risk management strategies.
This version of the NIST Digital Identity Guidelines offers an all-inclusive, secure and trusted path from creating to using online identities. It imposes stringent security requirements, such as authenticating cryptographically signed assertions by identity providers using authentication protocols; additionally it specifies standard technical protocols to securely exchange them. Federated identity management significantly enhances user experience while decreasing risk by centralizing identity management with trusted third parties.
SP 800-63-4 formally introduces remote identity proofing for IAL2, deprecates email OTP authentication, and downgrades SMS-based authentication to AAL1. Furthermore, these guidelines mandate phishing-resistant MFA as a requirement of AAL2 and AAL3 specifications and integrate device-bound and syncable FIDO Passkeys (both device-bound and syncable) into these specifications for AAL2, AAL3 and FAL requirements.
Compliance
As part of the enrollment process, applicants submit identity proofing evidence and self-assert their core attributes, which will then be verified and linked back to their claimed identity by an fedramp high identity proofing Provider and stored by the CSP for future verification. CSPs create subscriber accounts to identify claimants and keep an overview of any authenticators associated with those subscriber accounts (refer to Section 3.1 of [SP800-63A] for details). Recipient parties then gain access to these authenticators via federated authentication processes. These authentication processes rely on the trust established between IdP and CSP (refer to [SP800-63A] for normative information and requirements), as well as subscribers being able to control and protect their own authenticators(s) against theft or loss.
FedRAMP High
The National Institute of Standards and Technology has long set industry-wide standards in business, science, and technology – from plumbing pressure-loss measurements to chemical element viscosities. NIST also sets cybersecurity standards with their Special Publication 800-63 framework that’s widely adopted across businesses worldwide.
The 2025 release of 800-63-3 marked an impressive transformation from checklist-based requirements to risk-based Digital Identity Risk Management (DIRM) process. Its new framework uses a tripartite model of Identity Assurance Level (IAL), Authenticator Assurance Level (AAL), and Federation Assurance Level (FAL), each dynamically selected for each transaction – providing a powerful way of aligning identity workflows with appropriate security and risk thresholds, user accessibility considerations included.
Ial3 identity verification software makes compliance simple through adaptive, context-aware validation. Zero Trust alignment with MFA, hardware authenticators and robust federation are key elements to meet the requirements of IAL3 while phishing-resistant authentication like FIDO Passkeys offer maximum AAL3 strength. Trustswiftly stands out as an industry leader when it comes to remote ial3 compliance; with proven, audit-ready solutions that support FedRAMP High authorization – discover how our full stack IAL3 solution can eliminate delays, audit headaches and budget overruns by agencies pursuing high authorization levels – get a quote now.
Identity Proofing
The National Institute of Standards and Technology’s Digital Identity Guidelines (documents 63A, 63B and 63C) serve as the global standard for creating secure identity systems that comply with relevant legislation. Their 2025 update sees a shift toward user-friendly authentication methods while still adhering to security, including requirements such as providing phishing-resistant technology and mobile first authentication methods. Furthermore, an assurance level for remote identity proofing was introduced, acknowledging technologies like mobile driver’s licenses or verifiable credentials as trusted sources of evidence.
Enterprises should address this challenge by considering business risk rather than technology when choosing assurance levels, with the IAL, AAL, and FAL definitions providing organizations with the flexibility needed to map identity workflows to appropriate security and usability thresholds. Levels don’t always need to match; lighter identity proofing (IAL1) may pair nicely with stronger authentication (AAL2) for example, or even two levels may serve as “sweet spots” of feasibility, risk reduction, and certification availability (IAL2/3 often come to dominate this aspect).
Our comprehensive identity verification solution, Trustswiftly, was specifically developed to meet assurance standards such as those found in NIST 800-63-4. With its flexible and scalable approach to secure access across employee lifecycle – from onboarding through credential resets and interview fraud. Furthermore, its defense-in-depth strategy makes Trustswiftly an ideal way to detect threat actors using techniques like proxy use or social engineering through providing an enhanced layered security pipeline.
