    YubiKey 5 FIPS Series
    The first FIPS validated FIDO2/WebAuthn, multi-protocol authenticator lineup

    Strong phishing resistant MFA for the AI age — in six small and durable form factors

    Phishing-resistant MFA
    Defeating AI-driven identity attacks

    In an age of deepfakes and digital deception, hardware keys provide the only unphishable anchor for identity security, neutralizing AI threats through physical, hardware-attested proof of presence.

    The YubiKey stores the authentication secret on a secure element hardware chip. This secret is never transmitted and therefore cannot be copied or stolen.

    The YubiKey 5 FIPS Series lineup makes it easy to deploy strong, scalable authentication that eliminates account takeovers from phishing attacks. The YubiKey combines hardware-based authentication and public key cryptography to ensure strong authentication and eliminate account takeovers.
