Can I still use my Dynamic 3DS rules with 3D Secure 2?
Yes, Dynamic 3DS can be used with both 3DS2 and 3DS1. Dynamic 3DS is used as a trigger for 3DS on the merchant or the company level as per the requirement of the merchant. After which Adyen's Authentication Engine decides between best routing for 3DS version, this is based on the performance of the particular card BIN on both 3Ds1 and 3Ds2.
Based on the performance, transactions are routed for maximum conversion rate.
