    The YubiKey C Bio FIDO Edition is a USB-C fingerprint security key for people who want passwordless sign-in or stronger MFA on accounts and services that support FIDO2/WebAuthn or U2F, with a PIN available as a fallback.

    Recommended For

    • Desktop-first users who want to use a fingerprint for FIDO2/WebAuthn passkey sign-ins or FIDO security-key MFA on supported accounts.
    • People who regularly sign in at a USB-C-equipped computer and prefer fingerprint authentication to entering a FIDO PIN, with a PIN available as a fallback.
    • Cloud-first workers or IT teams securing supported services—such as Google or Microsoft accounts—with hardware-based FIDO login across desktop browsers and operating systems.
    • Users who only need FIDO security-key authentication and handle one-time codes separately in a password manager or authenticator app.
