To be compliant with Strong Customer Authentication (SCA) regulations, you will need to implement either the Payment Intents API or the new Stripe Checkout.

Payment Intents API

The Payment Intents API provides dynamic control over when and how SCA is required, adding access to 3D Secure 2 (3DS2) when 3DS2 is supported by cardholder banks.

New Checkout

Stripe Checkout is a pre-built solution created by Stripe using the the Payment Intents API. Checkout offers a Stripe-hosted and maintained end-to-end experience for you, ensuring that your business and integration are prepared for future regulations with minimal work required.
