Dynamic 3D Secure is a security protocol used for online transaction
verification and fraud prevention. It applies to websites or mobile
applications that support PingPongCheckout, adding an additional security
layer during the payment process. The system automatically determines whether
to enable 3D authentication based on risk assessment. The authentication
process includes two methods: Frictionless, which requires no user
interaction, and Challenge, which requires additional verification.

3D Secure is a security protocol used to verify online transactions and prevent fraud in e-commerce. It requires cardholders to enter a password or one-time code before completing a transaction, thereby adding an additional security layer to the payment process.
When your website or mobile application supports 3D Secure, the PingPongCheckout request for sending payments will determine whether the payment goes through 3D Secure authentication.
## 3D Secure Authentication Process
### Frictionless
In the Frictionless process, buyers, issuers, and card schemes exchange all necessary information in the background using the shopper's device fingerprint for passive authentication. The transaction is completed without further shopper interaction.
### Challenge
In the Challenge process, the bank or payment processor automatically creates a 3D challenge page for the cardholder, requiring additional interaction from the shopper. The issuing bank ensures transaction security through biometric identification, two-factor authentication, or similar methods based on SCA authentication factors.
Once the cardholder completes the authentication steps on the 3D challenge page, their identity will be verified, and the bank or payment processor can decide whether to approve the transaction.
## Default 3D Security Rules
Generally, PingPongCheckout provides default 3D security rules, and the PingPongCheckout risk control engine will decide whether the current transaction needs to enable 3DS authentication.
| Strategy | Description | 3DS Component Integration | Additional Requirements |
|:----:|:--------------:|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------:|:--------------:|
| Every Transaction 3D | 3D Secure always enabled | | |
| Intelligent Decision | Smart decision based on cardholder behavior characteristics | | customer.email |
## Merchant Autonomous Decision
If PingPong's default rules cannot meet your custom requirements, PingPongCheckout provides the capability for merchant autonomous decision.
You can decide whether to enable 3DS authentication through the `executeThreeD` parameter in the API according to your own business scenarios.
::: danger Note
Whether it can be enabled needs to be evaluated based on merchant risk situation and chargeback performance. If needed, you can contact technical support to enable the configuration.
