Introduction
Authorization server, also known as "auth server," is a crucial component of the OAuth 2.0 authentication framework. Its primary function is to verify and authenticate user credentials and issue access tokens that can be used to request protected resources from an API. In this article, we will explore the concept of authorization servers, its purpose, and its role in secure API communication.
1. What is an Authorization Server?
An authorization server is a part of the OAuth 2.0 protocol that grants permissions for accessing protected data on behalf of resource owners. It validates the end-user's identity, verifies access rights, and issues access tokens that allow clients to access protected resources through APIs securely. The authorization server works in conjunction with the authentication server, which authenticates the user's credentials.
2. How does it work?
To gain access to a protected resource, a client first requests authorization from the authorization server by presenting an authorization grant. The authorization server then authenticates the user, validates the authorization grant, and issues an access token to the client. The client can then use this access token to request access to the protected resource from the API server. The authorization server verifies the access token and either allows or denies access to the protected resource.
3. Why is it important?
Authorization servers play a crucial role in securing API communication. By issuing access tokens and verifying them before granting access to protected resources, they ensure that only authorized parties can access sensitive data. This enhances privacy and security by preventing unauthorized access to data and resources.
4. Conclusion

They play a critical role in securing API communication by authenticating users, verifying access rights, and issuing access tokens. This ensures that only authorized parties can access sensitive data and resources, thereby enhancing privacy and security. Overall, authorization servers are crucial for any system that requires secure API communication.
