WWPass Strong Customer Authentication is a passwordless authentication solution designed for financial institutions and insurance companies. The product eliminates the use of usernames, passwords, one-time passwords (OTPs), and transaction authentication numbers (TANs) by implementing a key-based authentication system. The solution provides multi-factor authentication that combines possession and knowledge or inherence factors. Users can authenticate across multiple independent resources using a single WWPass Key while maintaining credential isolation between accounts through directed identity. The system supports various hardware form factors including mobile applications, USB-NFC fobs, and smartcards. WWPass includes encryption capabilities and digital signature functionality, enabling secure communication between financial institutions and customers. The product implements self-service key management to reduce administrative overhead. The authentication procedure is separated from identification and authorization processes. The solution is designed to comply with PSD2 Directive requirements for strong customer authentication in the European financial services sector. It also addresses GDPR, NIST, PCI DSS, and FIPS 140-2 compliance requirements. The system aims to prevent identity theft and unauthorized information flow by replacing traditional credential-based authentication methods.
