Your Stripe account controls the level of authentication you require for customer payments. You can read more about this here.


Your Stripe account's default authentication setting is "Request 3DS if 3D Secure is required for card".



You can change this setting in your Stripe account here, e.g. to "Request 3DS if 3D Secure is recommended for card" or to "Request 3DS if 3D Secure is supported for card".
