NIST 800-63-4 outlines a fundamental Digital Identity Risk Management framework. It establishes assurance levels for identity proofing, authentication, and federation to enable more adaptive risk management. In particular, email OTP and SMS authentication have been deprecated while more secure authenticators like FIDO Passkeys have been promoted as viable solutions.

Fischer Identity's comprehensive IAM solutions meet these new requirements with their risk-based approach that balances business and security objectives.

Verification

NIST 800-63-4's 2025 release represents a dramatic transition away from checklist-based requirements toward risk-based Digital Identity Risk Management framework. At its core lies HYPR Affirm, which uses this framework for identity proofing and authentication services throughout all stages of workforce digital lifecycle verification - chat, video, facial recognition with liveness detection capability, document authentication services and step-up reproofing depending on risk levels are just some of the areas it serves. Discover more about identity verification softwares by clicking here or checking out our site.

Organizations now focusing on risk-based identity workflows can match authentication levels to security and risk thresholds, enabling them to meet compliance while providing seamless user experiences. For instance, deprecation of knowledge-based authentication and SMS one-time passwords from IAL1 shows recognition that these methods are vulnerable to social engineering attacks such as SIM swapping. By contrast, IAL2 sets a baseline for phishing-resistant multifactor authentication (MFA), solidifies passkeys as strong authentication mechanism, and officially recognizes mobile driver's licenses or verifiable credentials as forms of evidence.

Compliance

Nist 800-63-4 ial3 compliance and governance requirements in security are constantly shifting, placing strain on traditional authentication workflows that may no longer meet new standards. Knowledge-based and SMS one-time passcodes that were once acceptable now leave users open to social engineering or SIM swapping attacks; hence no longer meeting even moderate assurance thresholds such as AAL2.

NIST SP 800-63 outlines a digital identity assurance model and processes for selecting assurance levels for ID proofing, authentication, and federation. These processes involve defining roles of CSPs, IdPs and RPs along with any necessary verification or validation processes.

SP 800-63 defines three assurance levels, from IAL1 to IAL3. While IAL1 requires no verification at all; IAL2 calls for moderate verification that balances usability and security; and finally IAL3 represents the highest level of assurance, with hardware-based authenticators that resist phishing and impersonation being mandatory - forcing organizations to assess their existing authentication infrastructure and take any necessary measures to remain compliant.

Fedramp

NIST's digital identity guidelines are an integral component of modern security, setting standards for authentication strength and encouraging secure federation. Their latest revision, NIST 800-63-4 IAL3, introduces new expectations for identity proofing as well as emphasizing phishing-resistant authentication methods and hardware-backed authenticators.

Ial3 identity verification software involves enrollees providing evidence that prevents more sophisticated attacks such as falsification, theft, and impersonation - the highest level of NIST ID verification necessary for fedramp high identity proofing. This requires either attending in person or remotely supervising sessions during which enrollees provide superior-strength evidence that ensures adequate protection from advanced attacks such as evidence falsification.

TrustSwiftly's FIDO certified passwordless authentication and nist ial3 verification solution, HYPR Affirm, helps businesses meet IAL3 requirements with an intuitive experience that includes chat, video conferencing, facial recognition with liveness detection capabilities, document authentication, cyber liability insurance premiums reduction, operational expenses savings and attack surface area reduction - much like how visitors or employees are verified prior to being given entry to an office space.

High Identity Proofing

Identity proofing solutions with high levels of assurance allow businesses to quickly verify an individual's real-world presence and match them up to their claimed identity, thus helping mitigate against fraud, cybersecurity attacks, financial loss and reputation damage.

Checking an individual's claimed identity involves comparing it with multiple data sources, including credit bureau header information; commercial identity graphs; specialty databases like OFAC watchlists or deceased records; as well as government records where accessible. It includes verifying their existence over time as well as assessing if the identity is synthetic.

Identity proofing must be seamless and non-intrusive for users, and compliant with federal regulations. Furthermore, identity proofing systems should support scaling to accommodate different levels of verification so as to protect business operations during diverse workforce scenarios and periods of higher risk.
