What Is SCA – Strong Customer Authentication?

WP Simple Pay Pro and Lite are fully SCA-ready utilizing 3D Secure 2 through Stripe. Please see this release post for more details about the European regulation and what’s been done in WP Simple Pay to adhere to the requirements.

You should not have to update anything in your Stripe or WP Simple Pay settings besides perhaps enabling 3D secure authorization emails. Use the 4000 0000 0000 3220 test card number on our demo site to trigger a 3D Secure challenge flow.
