IAL1 | Name and birth date were self-asserted. |
IAL1.2 | An unspecified ID was used to verify name and birth date. |
IAL1.4 | A US state-issued photo ID or nationally-issued photo ID was used to verify name and birth date. |
IAL2 | Either remote or in-person identity proofing is required. IAL2 requires identifying attributes to have been verified in person or remotely using, at a minimum, the procedures given in NIST Special Publication 800-63A. |
IAL3 | In-person identity proofing is required. Identifying attributes must be verified by an authorized CSP representative through examination of physical documentation as described in NIST Special Publication 800-63A. |
