NIST’s Identity Verification Level 3 (IAL3) represents the highest standard in identity verification. This process includes in-person or remote session supervision by a CSP representative and comparisons of enrollee biometrics against ID evidence to detect fraud attacks such as spoofing. Furthermore, hardware authenticators and stringent chain of custody processes may be needed.

Trust Swiftly helps organizations meet IAL3 compliance through passwordless authentication and identity verification services. We manage retention schedules, supervise agents, and specialized hardware kits so your business meets IAL3 requirements.

IAL3 2026 Requirements

Verification using IAL3 involves face-to-face interaction with an on-site CSP representative and physical comparison of enrollee biometrics against those from identity evidence (such as photos, driver’s licenses or passports). It provides the most robust level of authentication and helps combat impersonation attacks, SIM swaps and MFA bypass attempts by securely linking biometric credentials with digital IDs of individuals.

IAL3 verification processes tend to be costly and time consuming; however, they provide the highest level of assurance against identity fraud, helping protect data assets with high value. Trustswiftly comprehensive nist ial3 verification solution, Affirm, was designed to meet workforce identity proofing needs throughout employee lifecycle by supporting both IAL2 and IAL3 verification through chat video video face recognition with liveness detection facial recognition document authentication as well as step up re-proofing based on risk; further minimizing cyber liability insurance costs by decreasing attack surface surface area.

Nist 800-63-4 ial3 compliance standards can be challenging for organizations with distributed teams, but Trustswiftly’s no code page on any device offers a cost-effective and more convenient method for rolling out compliance with this standard. An agent connects directly with the user for proofing sessions in real time without needing to customize kiosks; instead it works across Windows, Apple and Android devices alike.

IAL3 Compliance

NIST’s Identity Proofing Layer 3 requirements represent the pinnacle of identity proofing, with on-site verification comprising remote session supervision, biometric comparison with liveness detection support, and enrollee biometric verification to authenticate claimed digital identities. This process ensures high-value attacks like impersonation, SIM swaps and MFA bypasses are limited by securely linking multiple authenticators (something you have, something you know and something you are) securely to one enrolled individual; further limiting document falsification or theft using rigorous chain of custody processes when dealing with hardware-backed authenticators such as the YubiKey security token.

This approach to authentication marks a substantial shift, from checklist-based requirements to risk-based Digital Identity Risk Management framework, prioritizing stronger phishing-resistant authentication methods and mandating continuous verification to remain vigilant for threats.

Trustswiftly’s FedRAMP-align IAL3 software makes it simple for organizations to meet these new regulations. By connecting users with an agent through a no code page that is easily accessed from any device, users connect with chat, video streaming and facial recognition with liveness detection in order to verify their identity – helping businesses meet IAL3 requirements while decreasing cyber liability insurance costs and operational expenses by fewer password reset requests. Trustswiftly also helps them meet IAL1 requirements by connecting users directly with an agent through kiosk apps or single browser pages which helps scan both their face and documents while cutting the number of steps required in meeting IAL1.

IAL3 Software

NIST SP 800-63-3 defines three identity assurance levels (IAL, AAL and FAL) which measure the strength of association between digital credentials and real identities. While IAL1 doesn’t require verification of claimed identities and does not pose any risks for relying parties, IAL3 mandates presenting superior-strength evidence which will then be checked against databases at issuing authorities including reporting whether this evidence has been reported stolen or lost.

For transactions that carry high stakes, such as accessing classified information or critical infrastructure systems by federal remote IT workers or accessing critical infrastructure systems via remote IT workers, IAL3 identity proofing solutions with hardware-anchored cryptographic verification are the only viable security posture that ensure ial3 compliance and operational resiliency. To meet such stringent standards for defensible root of trust in this environment, organizations must move from traditional software-only IAL2 workflows towards an identity proofing solution capable of meeting them — to achieve it they must move away from legacy software-only IAL2 workflows towards identity proofing solutions capable of meeting defensible root of trust requirements in this environment.

Trustswiftly’s FedRAMP-compliant IAL3 Supervised Remote Identity Proofing platform embodies this key innovation by shifting identity verification away from individual devices to managed, tamper-evident hardware. This architectural modification instantly and permanently eliminates injection attacks by creating a secure execution environment – effectively dispensing with smartphones, silicon masks or AI-generated deepfakes that often defeat software-only solutions. Thus, the platform provides unbreakable cryptographic chain of custody for high-assurance identity proofing, creating a fully scalable, tamper-evident security architecture compliant with IAL3 that ensures both long-term cybersecurity and compliance.

IAL3 Hardware

TrustSwiftly can assist your organization in meeting IAL3 requirements or just making sure your systems are secure, whether or not the requirement exists within FedRAMP templates or security requirements matrix. We have reviewed both, confirming that the “High” baseline requires IAL3.

Identity Assurance Level 3 (IAL3) provides unsurpassed confidence in digital identities by mandating on-site or remote supervised sessions during which enrollees submit superior-strength proof of their identities and biometrics, providing ample protection against attacks such as falsification and theft of evidence as well as impersonation attacks, which helps establish trusted relationships and validate credentials in real time.

An effective fedramp high identity proofing should provide an on-site or remote supervised experience during which biometric comparison (facial recognition or voice) and hardware level verification ensure the enrollee matches up with his/her claimed identity and strongest piece of evidence (biometric comparison or hardware level verification). It should also support hardware level verification to make sure devices in use correspond with those registered for enrollment.

TrustSwiftly’s ial3 identity verification software can fulfill this need by offering remotely yet supervised identification proofing using chat, video and facial image recognition with liveness detection capabilities and step-up reproofing based on risk. This reduces cyber liability insurance costs as well as operational expenses and decreases attack surface areas of digital products and services.
