YubiKey 5 Cryptographic Module

Yubico, Inc. - FIPS 140 #3914

historicalLevel 2

The YubiKey 5 cryptographic module is a secure element that supports multiple protocols designed to be embedded in USB and/or NFC security tokens. The module can generate, store, and perform cryptographic operations for sensitive data and can be utilized via an external touch-button for Test of User Presence in addition to PIN for smart card authentication.The module implements five major functions - Yubico One Time Password (OTP), FIDO2, PIV-compatible smart card, OpenPGP smart card and OATH OTP authentication.
