OneVisage Premier Keys is a two-factor authentication solution that uses FIDO2 protocol and 3D facial biometric recognition to authenticate users for laptop logins, server access, and enterprise applications. The system performs authentication in approximately 200 milliseconds using built-in 3D cameras or FIDO2-compatible 3D webcams. The solution eliminates the need for passwords, PIN codes, OTPs, PKI dongles, and password managers by implementing FIDO2 challenge-response authentication protocol. It automatically verifies website URLs to prevent phishing attacks and blocks authentication attempts to fake or undeclared domains. Premier Keys stores biometric tokens in a mobile wallet or enterprise application that users control, rather than in centralized databases. The system implements continuous authentication to prevent session hijacking and includes protections against device theft through mobile biohash vault technology. The product is designed to comply with data privacy regulations including GDPR, CNIL 2019-01, FDPA, CCPA, DPDP Act, and PDPL. It provides protection against multiple attack vectors including phishing, man-in-the-middle attacks, MFA bombing, replay attacks, credential stuffing, database breaches, social engineering, SIM swapping, keyloggers, and brute force attacks. The authentication system supports Windows Hello replacement scenarios and can be deployed for securing databases and Linux servers. It is designed for organizations requiring passwordless authentication with enhanced security beyond traditional MFA methods.
