Case Study: WithLess achieves PSD2 compliance and seamless facial-biometric authentication with Keyless

Adopting biometric authentication to achieve PSD2 compliance and meet Strong Customer Authentication requirements

WithLess, a European finance automation platform focused on software subscription and renewal management, needed to replace SMS-based two-factor authentication to improve security and user experience while meeting PSD2 Strong Customer Authentication (SCA) requirements. They engaged Keyless to implement biometric authentication—using Keyless’ facial biometric solution and SDK/API—to meet regulatory requirements and modernize login flows.

Keyless delivered a web- and mobile-ready facial biometric system with step-up authentication for high‑assurance actions and PSD2 SCA features that dynamically link transaction amount and account number. The integration was completed in under two weeks via Keyless’ SDK, enabling WithLess to achieve PSD2 compliance in a matter of weeks, eliminate SMS OTP attack vectors like phishing and SIM swapping, and improve overall user experience without disrupting operations.
