# 3D Secure authentication for marketplaces (/platforms/checkout/advanced/customize/3d-secure)



Use 3D Secure to authenticate card holders through card issuers. It reduces the likelihood of fraud when you use supported cards and improves transaction performance. A successful 3D Secure authentication can shift liability for fraudulent chargebacks from you to the card issuer.

3D Secure authentication is performed only if the card is enrolled for the service. When your customer submits their card details on your website for processing, you have the option of triggering 3D Secure. When triggered, customers are prompted by their card issuing bank to complete an additional verification step to enter a one-time or static password, depending on the implementation.

## How it works [#how-it-works]

This demo shows a checkout flow that triggers authentication with 3D Secure.
