FIDO (Fast Identity Online) is a modern authentication standard that enables phishing-resistant multi-factor and passwordless authentication using hardware-backed cryptographic methods. It consists of open protocols, including WebAuthn and CTAP, that enable secure, seamless access without relying on passwords. Yubico’s YubiKeys implement FIDO2 and U2F standards, providing strong, hardware-based security keys that replace weak passwords with cryptographic credentials. This approach enhances business security by preventing phishing, replay, and man-in-the-middle attacks while simplifying user experience and administration for enterprises.
