Authentication and authorization are fundamental aspects of securing web applications, APIs, and other software systems. In Python, decorators offer a concise and elegant way to enforce access control policies by wrapping functions with authentication and authorization checks.

In this article, we’ll explore how decorators can be leveraged for authentication and authorization, providing practical examples and insights to help you bolster the security of your Python applications.

Understanding Authentication and Authorization

Authentication verifies the identity of users, ensuring they are who they claim to be. Authorization, on the other hand, determines whether an authenticated user has the necessary permissions to perform a specific action or access a particular resource.
