Thoughts, tutorials, and insights on software development and technology
Authentication and authorization are often confused, yet they serve different purposes in application security. Authentication verifies a user's identity, while authorization determines what they are allowed to access. Understanding the distinction is essential for building secure APIs and web applications.
