NIST 800-63A IAL3 identity proofing is a more advanced level of identity verification, which requires additional evidence, validation and verification requirements in order to prevent impersonation attacks and identity proofing errors. Verification methods approved for use with IAL2 digital evidence include local activation factors (e.g. PKI credentials on smart cards) and the presentation of cryptographically verifiable attribute bundles; alternative pathways include trust referees.
