OAuth & OpenID Connect Implementation – 5 Practice Tests

This course provides a clear and structured introduction to OAuth 2.0 and OpenID Connect, focusing on how modern authentication and authorization are implemented in real-world applications.

You will begin by understanding OAuth 2.0 fundamentals, including its purpose and how it enables secure delegated access. The course explains the key OAuth actors such as resource owner, client, authorization server, and resource server, helping you understand how these components interact during authentication flows.

As the course progresses, you will take a deep dive into OAuth 2.0 grant types, learning when and why different grant types are used. This builds a strong conceptual foundation for implementing secure authentication mechanisms in modern applications.

You will then explore JSON Web Tokens (JWT), understanding how tokens are structured, signed, and used to securely transmit claims between systems. This section helps you clearly understand token-based authentication, which is widely used in APIs and distributed systems.

The course also introduces OpenID Connect, explaining how it extends OAuth 2.0 to provide identity information and user authentication. You will learn the role OpenID Connect plays in modern identity solutions.

Finally, the course provides a high-level overview of how security is implemented in ASP.NET Core, connecting OAuth and OpenID Connect concepts to real application scenarios.

Each topic is explained through concise video lectures, supported by practice tests to reinforce understanding. By the end of this course, you will have a solid conceptual understanding of OAuth 2.0 and OpenID Connect and be well prepared to work with modern authentication systems.
