HYPR Authenticate App is a passwordless multi-factor authentication (MFA) mobile application designed to improve security and provide a faster, simpler approach to authentication. It transforms smartphones into FIDO2 passkeys, replacing passwords and shared secrets with secure public key cryptography. The app offers a mobile-initiated login experience for workstations, virtual desktops, and various other systems. HYPR Authenticate implements Zero Trust authentication principles, providing continuous security assessment and authentication that adheres to NIST AAL3 guidelines. It supports both online and offline authentication modes and can be integrated with various systems, Identity Providers (IdPs), and applications across an enterprise. The solution uses hardware-backed security and encrypts private keys on trusted user devices, offering phishing-resistant authentication that protects against credential phishing, push bombing, and other credential-based attacks.
