2.2.2 Authenticator and Verifier Requirements

Authenticators used at AAL2 SHALL use approved cryptography. Cryptographic authenticators procured by federal agencies SHALL be validated to meet the requirements of [FIPS140] Level 1. At least one authenticator used at AAL2 SHALL be replay-resistant, as described in Sec. 3.2.7. Authentication at AAL2 SHOULD demonstrate authentication intent from at least one authenticator, as discussed in Sec. 3.2.8.

Communication between the claimant and verifier SHALL occur via one or more authenticated protected channels.

Cryptography used by verifiers operated by or on behalf of federal agencies at AAL2 SHALL be validated to meet the requirements of [FIPS140] Level 1 unless otherwise specified.

Verifiers SHALL offer at least one phishing-resistant authentication option at AAL2, as described in Sec. 3.2.5. Federal agencies SHALL require their staff, contractors, and partners to use phishing-resistant authentication to access federal information systems. In all cases, verifiers SHOULD encourage the use of phishing-resistant authentication at AAL2 whenever practical since phishing is a significant threat vector [IC3].
