OAuth 2.0
OAuth 2.0 is an authorization framework that enables third-party applications to obtain limited access to user accounts on HTTP services, such as social media platforms or cloud storage. It allows users to grant access to their data without sharing their credentials, using tokens instead of passwords. This standard is widely used for secure delegated access in web, mobile, and desktop applications.
Developers should learn OAuth 2.0 when building applications that need to integrate with external services like Google, Facebook, or GitHub, as it provides a secure way to handle user authentication and authorization without managing passwords. It's essential for implementing features such as social login, accessing APIs on behalf of users, or enabling data sharing between services, reducing security risks and improving user experience.
