EzAuth by OCTATCO is a FIDO-certified, integrated passwordless multi-factor authentication (MFA) solution implementing FIDO UAF, FIDO U2F, and FIDO2 standards. The platform integrates both PC-embedded fingerprint sensors and external biometric security keys, while supporting authentication across Windows and Linux environments, PCs, smartphones, and tablets. The solution enables multiple authentication methods including smartphone biometrics (fingerprint, Face ID, Touch ID), mobile OTP, mobile push notifications, PIN, security questions, email OTP, SMS authentication, and FIDO security keys. Authentication data and personal information are stored in hardware secure areas like TPM to ensure fingerprints and private keys remain protected on devices. EzAuth supports integration with VPNs and remote access servers through RADIUS protocol, and provides 1:N fingerprint recognition capabilities. The system performs authentication 10 times faster than regular password authentication and 5 times faster than OTP authentication while protecting against phishing, spoofing, sniffing, and man-in-the-middle attacks.
