The YubiKey 5C NFC FIPS is FIPS 140-2 certified (Overall Level 1 and Level 2, Physical Security Level 3) and based on the YubiKey 5C NFC. The YubiKey 5C NFC FIPS has five distinct applications, which are all independent of each other and can be used simultaneously. Note: The YubiKey 5 FIPS Series does not support OpenPGP. Should you need this functionality, you will need either the YubiKey FIPS (4 Series) or the YubiKey 5 Series (non-FIPS).

Interface

The YubiKey 5C NFC FIPS uses a USB 2.0 interface as well as an NFC interface. All of the applications are available through both interfaces.

Applications

FIDO2

The FIDO2 application allows for secure single and multi-factor authentication, and can store up to 25 resident credentials. These credentials, which are protected by a PIN, enable passwordless login, where the YubiKey, unlocked by a PIN and authorized by touch, can log you in to your accounts without entering a username or password. The FIDO2 application is FIDO certified.

USB/NFC Interface: FIDO
