At Keyless, we’re on a mission to provide businesses with the smoothest, safest, and most private passwordless authentication possible. Passwords, one-time codes, and FaceID all have their drawbacks, whether it's security risks, high costs, or poor user experience. We offer a simpler, safer, and more cost-effective alternative. Zero-Knowledge Biometrics (ZKB), our award-winning biometric system, is the only technology to date that combines the strengths of the two existing systems, providing the user experience of centralized biometrics with the privacy of local biometrics.

In addition, ZKB does not store any biometric data anywhere, ensuring maximum privacy and security for our users. Keyless is also completely device-agnostic. Users can enroll on one device and authenticate on another. All users need is a front-facing camera. Keyless is available for both consumers and employees, dramatically reducing ATO fraud while enhancing the user experience. Our MFA technology is resistant to phishing and compliant with all major data protection and payment regulations. Our solutions are used to authenticate users during logins, transactions, step-up actions, and account recovery, delivering the most secure and frictionless passwordless MFA experience available.
