I just use a Visa’s bank card from the API Explorer’s «3D Secure - Auth Payment page» with my own cardholder name.
Maybe there are some other test cards?
For example, Stripe provides:
-
Dedicated bank cards for the following 3D Secure cases:
- 3D Secure is supported but not required on this card.
- 3D Secure is supported and required on this card.
- 3D Secure is not supported or required on this card.
- Dedicated bank cards for getting some specific error responses.
