    LOADING...

    The Yubico Security Key C NFC is a compact FIDO2/WebAuthn and U2F security key for people who want hardware-backed passkey or two-factor sign-in on supported accounts, using USB-C or NFC with compatible devices.

    Recommended For

    • People who want a physical, phishing-resistant way to sign in to FIDO2/WebAuthn- or U2F-compatible accounts, such as Google, Microsoft, Dropbox, or supported password managers.
    • USB-C laptop users who want to authenticate with a touch of the key, and use the same key with supported phones through NFC; hands-on testing found both connection methods useful for account sign-ins.
    • People who want to keep FIDO2 passkeys on a separate physical key and carry it between devices, rather than relying only on a device-stored passkey.
    • Users seeking a compact, battery-free security key to keep on a keychain for regular sign-ins to supported online accounts.
