Last updated May 2021

Verify your customer's identity simply and seamlessly to minimize fraud. Use our strong customer authentication to benefit from liability shift.


3DS allows you to meet the Strong Customer Authentication (SCA) requirement under the PSD2 regulation as well as shifting liability for fraudulent transactions to the issuer.

Liability shift

Liability for fraudulent transactions passes to the issuer when 3DS is applied. A successful frictionless/challenge outcome is only an indication of liability shift. The shift itself happens when the 3DS data is applied in the payment request.
