Supplemental Guidance

Acceptance of Personal Identity Verification (PIV) credentials from other federal agencies applies to both logical and physical access control systems. PIV credentials are those credentials issued by federal agencies that conform to FIPS Publication 201 and supporting guidelines. The adequacy and reliability of PIV card issuers are addressed and authorized using [SP 800-79-2](#10963761-58fc-4b20-b3d6-b44a54daba03).

Practitioner Notes

This enhancement requires your systems to accept PIV credentials from other federal agencies — enabling cross-agency authentication with government smart cards.

Example 1: Configure your Active Directory to trust the Federal PKI certificate chain so that employees from other agencies can log in with their PIV/CAC cards.

Example 2: Enable cross-certificate trust in your PKI infrastructure to accept certificates issued by other federal agencies' certificate authorities.
