In this advanced quest, you will dive deep into the world of API security using JSON Web Tokens (JWT) and OAuth2 protocols. You'll start by understanding the fundamental concepts of authentication and authorization, exploring how JWTs work and their advantages over traditional session-based authentication methods. Next, you will learn how OAuth2 can be implemented to secure APIs effectively, allowing third-party applications to access user data without exposing sensitive credentials. Through practical exercises, you will create APIs that utilize JWT for secure communication, implement OAuth2 workflows, and handle token expiration and refresh strategies. By the end of this quest, you will be equipped with the knowledge and skills necessary to secure your applications against common vulnerabilities.
