API Authentication for Azure Form Recognizer

For API authentication, I understand that Azure Form Recognizer uses "Ocp-Apim-Subscription-Key" which is the Azure Subscription ID. Also, shouldn't there be an API key as well, which we should be using for accessing any API across the subscription? Or is it there? Also, once the authentication is successful, do we have a kind of token which ensure the user remains authenticated for some time? How does this work? Moreover, as per the attached image, there are two API keys involved while using the AFR APIs. What is the use of those two keys?
