FIPS 140-2 validated security keys
Meets strict compliance requirements for organizations that require additional FIPS certifications. For example, prescriptions from foreign banks or government institutions from the USA and other. If you do not have such conditions for using security keys, then return to the consideration of the Yubikey 5C NFC.
Each key in Yubico's FIPS series is individually tested. FIPS 140-2 validated (Common Level 1 and Level 2, Physical Security Level 3).
Meets the highest Authenticator Assurance Level 3 (AAL3) according to NIST SP800-63B guidelines.

Testing the cryptographic module for the YubiKey
Cryptographic module validation testing is performed using Derived Test Requirements [DTR] for FIPS PUB 140-2, Security Requirements for Cryptographic Modules. The DTR lists all the requirements for vendors and testers to verify a cryptographic module, and it is the basis of testing performed by CST's accredited laboratories.
