Integrate with PayShield for 3D Secure 2 (3DS2) authentication using PayShield's JavaScript-based 3DS SDK. The subsequent pages provide an overview of the [3DS DOM elements](/3dsecure2+/3ds-dom-elements.md) and describe how to connect to the [3DS SDK](/3dsecure2+/3ds-sdk-options.md) and the various options available.

We also have a demo payment page that shows how simple it is to integrate. Instructions for the demo payment page are in the [3DS Demo Payment Page](/3dsecure2+/3ds-demo-payment-page.md) section.
