This allows you to use your own SSL certificate for secure communication between your application and the identity provider.
* Option A: Correct. A custom API domain enables you to configure an SSL certificate for secure communication with external identity providers.
* Option B: Incorrect. A central login page is unrelated to configuring SSL certificates for encrypted communication.
* Option C: Incorrect. "Identity" is too vague and does not address the need for SSL configuration.
* Option D: Incorrect. Trusted site URLs are used to define allowed origins for CORS (Cross-Origin Resource Sharing) but do not involve SSL certificates.
