It meets Authenticator Assurance Level 3 (AAL3) under NIST SP800-63B with FIDO2, U2F, PIV, Yubico OTP, OATH (HOTP/TOTP), and OpenPGP support, plus the new 140-3 cryptography (RSA-3072, RSA-4096, Ed25519, SCP11).Built for regulated industries, federal agencies, and high-security enterprises needing cross-platform authentication with validated cryptographic modules, it works across macOS, iOS, Windows, Linux, and Android (via USB-C). The YubiKey 5 FIPS Series is uniquely DoD-approved for both PKI credentials and FIDO2 passkeys on a single device.
