NIST 800-63-4 raises the bar for digital identity by mandating extensive identity proofing and phishing-resistant authentication, in addition to mandating CSPs create subscriber accounts containing authenticators (passwords or PINs) associated with them.
NIST's 2025 Digital Identity Guidelines contain major revisions that set aside email OTP authentication and downgrade SMS-based authentication methods, while simultaneously incorporating Passkeys and cementing FIDO2 as the top standard for strong cryptographic authenticators.
Verification
Nist ial3 verification helps prevent fraud and cybercrime, as well as often being required of online activities in security, healthcare and financial transactions. Compliance regulations also mandate organizations integrate digital identity verification into their products and services - for instance the National Institute of Standards and Technology has three identity assurance levels to make sure a person's claimed identity corresponds with his/her actual existence in reality.

IAL1 requires claimants to present evidence supporting their real-world identity, such as photo ID or documents. This allows the RP to link this real-life identity with the CSP-issued federated identifier, while using an assertion including CSP-signed attribute bundle and additional attributes for access or authorization decisions (refer to Section 5 of SP800-63A for details and normative requirements).
Compliance
Regulatory compliance is one of the primary motivations behind businesses adopting digital identity verification solutions, as it helps prevent fraud and cyber attacks as well as fulfill various statutory requirements in various sectors. Many industries - particularly security and healthcare services - mandate identity proofing processes with stringent standards to meet nist 800-63-4 ial3 compliance.
The digital identity guidelines consist of three assurance levels: IAL1, IAL2 and IAL3. At this level, claimants need only demonstrate basic control over an authenticator that's linked to their subscriber account; at IAL2 more rigorous proofing methods are required and security technologies more sophisticated, while for IAL3 an on-site attended identity proofing session conducted by a trained CSP representative along with biometric proof (such as live selfie) is mandatory.
These guidelines offer detailed information and normative requirements regarding identity proofing, enrollment, and management processes as well as authentication protocols and federation assertions used at different assurance levels.
Fedramp
Approving their cloud service providers (CSPs) under FedRAMP is an integral step to doing business with federal agencies, yet the process can be complex and time consuming. Therefore, CSPs must familiarize themselves with current updates and best practices in order to avoid common pitfalls in gaining approval.
FedRAMP, or the Federal Risk and Authorization Management Program, is a government-wide program that provides streamlined security assessment, authorization and continuous monitoring for cloud products and services. FedRAMP enables agencies to quickly adopt secure cloud solutions while expediting delivery of an inclusive security baseline for all agencies involved.
fedramp high identity proofing is an offshoot of FISMA, originally written to protect federal information. However, over time it was expanded to encompass cloud technology use as well. As part of a new law mandating standardized security protocols for federal agencies this led to FedRAMP and related processes including its Joint Authorization Board and Program Management Office being created. These processes ensure consistency throughout federal agencies - something essential when working with or proposing business deals with them.
High Identity Proofing
Identity proofing can be an effective means of combatting online fraud, including account takeover and other types of online theft. Ial3 identity verification software offer an industry-leading strategic tool with multiple risk controls - including our DocV capability - designed to ensure robust and reliable verification of digital IDs.
First, identify what kind of identity verification the RP needs. This may involve deciding if personal data needs to be provided for digital transactions and validating core attributes or accepting self-asserted attributes as acceptable solutions.
CSPs can offer redress mechanisms to assist applicants who are unable to complete identity proofing processes due to limited evidence, verification methods or authentication processes. These mechanisms must be easily accessible by applicants; their use must include conducting an in-depth privacy impact analysis of applicant reference processes as detailed in Sec 3.1 of [SP800-63]. In addition, CSPs should make their documented procedures and practice statements available to RPs that use its identity proofing services.
Attaining an Identity Level 3 certification involves providing and verifying strong identity evidence belonging to an individual, along with in-person or remote identification, strong biometric matching technology, and strong biometric matching to reduce false positives.
This can be accomplished using solutions such as HYPR, which combines chat, video, facial recognition with liveness detection and document authentication to support IAL2 and IAL3. Furthermore, step-up reproofing based on risk is supported.
NIST IAL3 verification
NIST has established Identity Assurance Levels (IALs), which indicate the degree of confidence that an claimed digital identity corresponds to its counterpart in real life. For high-risk transactions where falsifying an identity could cause serious harm - for instance gaining access to classified data or critical infrastructure systems - an IAL3 is reserved as a minimum level.
Organizations seeking IAL3 must use superior-strength evidence to verify ownership of proofing events by physical applicants - typically an image of government-issued ID document - which they submit. An ID&V solution can then use both strong and fair evaluation methodologies and scores when comparing this evidence against physical applicants.
IAL3 requires that every enrolled user be present during a verification session, which can be carried out using kiosks or live human agents. While this approach adds complexity to the process and necessitates additional training and documentation efforts, it also increases costs related to hardware logistics, supply chain management and security auditing.
IAL3 identity proofing
IAL3 Identity Proofing offers an exceptionally high level of assurance that the digital identity of an individual matches up with their physical one. The process includes on-site verification and the presentation of strong identity evidence from authoritative sources that is verified with biometric comparison and direct oversight to prevent impersonation or fraud.
CSPs typically find this higher level of assurance more expensive to implement, as it only applies in specific instances such as secure physical access checks or benefits eligibility checks requiring it. For most businesses, IAL2 with strong biometric matching will suffice.
TrustSwiftly's managed solution or its self-hosted version are both capable of authenticating at this level, while TrustSwiftly can be set up on customer hardware for self-hosted authentication at this level. IAL3 requires hardware with very high performance to accommodate different identity proofing methods designed to be replay resistant; additionally it mandates the presence of a trusted referee during proofing sessions.
IAL3 compliant solution
IAL3 is the highest level of authentication under the NIST Digital Identity Guidelines and requires providing superior-strength identity evidence as well as being verified in person with a supervisor. Furthermore, this process includes strong binding mechanisms, device ID identification and biometric capture onsite as part of its requirements. Although time-consuming and costly to perform this level of authentication may provide best protection from cybercriminals and phishing scammers.
Authentication and Lifecycle Management addresses how an individual can safely verify their identity to a CSP and assert it at an assurance level (AAL) specified. Furthermore, this practice defines requirements for federated identities with assertion levels at AAL2. For more information on NIST 800-63A IAL3, click here or check out our official site.
NIST 800-63A IAL3 2025 release has moved away from checklist-based verification towards a risk-based identity framework that prioritizes stronger authentication protocols that can resist phishing attacks. Furthermore, usability was prioritized over security for user experience and accessibility purposes - this shift helps address user friction issues as well as adoption hurdles.
