In this advanced quest, you will dive deep into the world of OAuth2, a protocol that allows secure authorization from third-party applications without sharing the user's credentials. Through a series of hands-on challenges, you will learn how to implement OAuth2 in your web applications, understand the different grant types such as Authorization Code, Implicit, Resource Owner Password Credentials, and Client Credentials, and explore how to secure APIs using access tokens. By the end of this quest, you will be equipped to design secure authentication flows and protect sensitive user information effectively. Prepare to tackle common pitfalls and security vulnerabilities in OAuth2 implementations, including token leakage and scope management, ensuring your applications are robust against attacks.
