For 3D Secure 2, the card issuer performs the authentication in your app or payment form. The shopper's identity may be verified using passive, biometric, or a two-factor authentication method. For more information, refer to 3D Secure 2 authentication flows.
Payments routed to redirect flow
It is possible that the authentication falls back to redirecting the shopper to the issuer's site. Therefore, we recommend that your integration also supports the redirect flow.
