What is FIDO2 in Cybersecurity?
FIDO2 is a set of standards from the FIDO Alliance and W3C that enable passwordless and phishing-resistant authentication. It combines WebAuthn (browser API) with CTAP (client-to-authenticator protocol) to let users sign in with security keys, platform authenticators, or biometrics. Credentials are bound to the origin, making phishing ineffective.
Why FIDO2 Matters for Your Cybersecurity Career
FIDO2 is the strongest form of phishing-resistant MFA available today. CISA and major tech companies actively promote FIDO2 adoption. Security engineers deploy FIDO2-compatible authenticators across organizations. Understanding FIDO2 sets candidates apart when applying for identity-focused cybersecurity roles.
