PSD2 SCA & Dynamic Linking

Designed for banks and fintechs, Keyless ensures PSD2 SCA compliance with two-factor authentication and in-built dynamic linking.

What is PSD2 SCA?

PSD2 SCA requires all EU banks to authenticate customers using two independent factors and dynamically link transaction amount with the user's account number.

Two factor authentication, one user action

Keyless is multi-factor by design, verifying a user's face and their device with a glance, fulfilling the mandate's MFA requirements.

Dynamic linking for payment authorization

Every transaction is tied to a unique code that includes the amount and recipient - meeting PSD2’s dynamic linking requirement without extra user effort.

Case study: International Bank

An international bank based in the EU was looking for a PSD2 SCA-compliant authentication solution that offered dynamic linking without increasing user friction.
Keyless was chosen due to its unique ability to independently authenticate possession and inherence without centrally storing biometric data.

Benefits of Dynamic Linking for Banking Compliance

Dynamic linking is essential for meeting regulatory requirements like PSD2 Strong Customer Authentication. It ensures that every transaction is tied directly to both the amount and the recipient, preventing fraud even if credentials are compromised. By combining dynamic linking with biometric authentication, banks can confirm not just the user’s intent, but also their identity, in real time. This creates a secure, user-friendly way to approve transactions while staying fully compliant with banking regulations.
