## Authorization Servers

Authorization servers are dedicated components in an authentication architecture that verify the identity of a user or application and issue access tokens. They act as the central authority for determining what a client is allowed to do within a system.

When a user logs in or an application requests access, the authorization server evaluates the credentials and scopes requested. If valid, it provides a time-limited token that the client can use to access protected resources.

This decoupling of authentication from resource management is a key feature of modern, secure API design. It allows for scalable and flexible access control across complex, multi-service trading platforms.
