# Using 3D Secure authentication with payments made through Stripe Billing

You can use [Radar rules](https://stripe.com/docs/radar/rules) to trigger 3D Secure authentication for payments made using [Stripe Billing](https://stripe.com/billing), including recurring subscriptions and invoices. This feature is disabled by default for charges where 3D Secure is available but not required, but you can [enable it](https://dashboard.stripe.com/settings/billing/automatic) in Radar if your Stripe integration supports 3D Secure via [Stripe Checkout](https://stripe.com/docs/payments/checkout) or our [Payment Intents](https://stripe.com/docs/payments/payment-intents) or [Setup Intents](https://stripe.com/docs/billing/subscriptions/payment#using-setupintents) APIs.
## Additional Information
* When this rule is enabled, it will only apply to payments made in live mode.
* 3D Secure authentication for [Strong Customer Authentication (SCA)](/questions/strong-customer-authentication-sca-preparation-and-resources) will always be triggered, regardless of whether or not you have this rule enabled.
