Using `3-D Secure` {#task_eyj_brc_mcc}
--------------------------------------

If you are going to use `3-D Secure`, you must have `Payer Authentication` enabled and have your Cardinal keys stored within the `Business Center`. To enable `Payer Authentication`, contact `Visa Acceptance Solutions` support or your account manager. Request that the `Payer Authentication` enablement include support for the direct integration method.  
After `Payer Authentication` is enabled, follow these steps to verify your `Payer Authentication` credentials:

1. Log in to your `Business Center` account.
2. Go to Payment Configuration \> Payer Authentication Configuration.
3. View the Org Unit ID, API Identifier, and API Key to verify your credentials.

Because you verified the `Payer Authentication` credentials and enabled the `3-D Secure` feature when you installed the Cybersource app, the transactions will support `3-D Secure` flows.
