FIDO Security Key – Passwordless Authentication Made Simple

What Is a FIDO Security Key?

A FIDO Security Key is a hardware-based device that offers passwordless login and multi-factor authentication (MFA) using industry-leading FIDO2, U2F, and WebAuthn protocols. It’s the fastest and most secure way to access your online accounts, corporate systems, cloud platforms, and web applications.

Why Choose a FIDO Security Key?

FIDO keys provide phishing-resistant authentication by replacing passwords with cryptographic login credentials. Trusted by enterprises, developers, and individuals, they ensure secure access with a single touch, tap, or NFC scan.

Whether you're securing Google Workspace, Microsoft 365, Facebook, GitHub, or enterprise identity providers like Okta or Duo, a FIDO-compliant security key offers strong two-factor, passwordless, or single sign-on (SSO) options.
