Cryptographic Module Validation Program CMVP

Certificate #3907

Details

Module Name
YubiKey 5 Cryptographic Module
Standard
FIPS 140-2
Status
Active
Sunset Date
4/21/2026
Overall Level
1
Caveat
When operated in FIPS mode, installed, initialized, and configured as specified in Section 3 of the Security Policy. The module generates cryptographic keys whose strengths are modified by available entropy.
Security Level Exceptions
  • Physical Security: Level 3
  • EMI/EMC: Level 3
  • Design Assurance: Level 3
  • Mitigation of Other Attacks: N/A
Module Type
Hardware
Embodiment
Single Chip
Description
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. The module implements several major functions - Yubico One Time Password (OTP), FIDO/FIDO2, FIDO/U2F, PIV-compatible smart card, OpenPGP smart card, and OATH OTP authentication.
