Multi-Pass by Kelvin Zero is a global access card and software solution providing secure biometric authentication. It uses a fingerprint sensor and contactless technology for easy authentication with a single tap. Multi-Pass enhances security by removing the need for passwords, which are vulnerable to being guessed or stolen. With biometric authentication in each card, it ensures only authorized users access sensitive information. Multi-Pass can be integrated with existing systems using the FIDO standard. It can be customized to provide a flexible and adaptable authentication solution. Multi-Pass offers a secure and convenient authentication method that is hard to replicate. It uses secure asymmetric cryptography and keeps private keys safe in a tamper-resistant smart card chip. The biometric fingerprint template is saved on the card, and biometrics are never stored online or on the device. Multi-Pass supports all major SSOs and open standards for rapid deployment. It provides password-free access to reduce phishing risks and simplify employee logins. Multi-Pass can be used for workstation logins, web services, apps, remote work access, and physical access. It leverages a secure, tamper-resistant chip for storing private keys and performing cryptographic operations. Multi-Pass can be integrated with existing access control systems and provides access to all enterprise resources with a single card.
