Understanding OAuth2 Authorization with Spring’s @EnableAuthorizationServer
Introduction
OAuth2 is a renowned authorization framework that facilitates third-party applications to gain limited access to user accounts on an HTTP service, such as Facebook, GitHub, and Google. In the realm of Spring, the @EnableAuthorizationServer annotation plays a pivotal role in integrating OAuth2 with your applications. This post will delve into the world of OAuth2 and the pivotal role of @EnableAuthorizationServer within the Spring ecosystem.
What is OAuth2?
OAuth2, standing for “Open Authorization version 2”, is the second iteration of a standard protocol that offers a method for clients to access server resources on behalf of a resource owner. At a high level, it is an authorization framework, not an authentication protocol, even though it’s often used in tandem with authentication mechanisms.
Background
The digital world has seen a massive increase in interconnected applications. As users, we’d want to utilize our data from one application in another without exposing our credentials. OAuth2 was developed to address this by allowing third-party applications to access user data without compromising security.
