The article titled “Learn how to secure Spring Boot applications using OAuth2 and OpenID Connect with practical examples” provides guidance on securing web applications built with Spring Boot using OAuth2 and OpenID Connect (OIDC). It emphasizes the importance of security in web applications and explains how OAuth2 can be used to authorize third-party applications to access user resources without sharing sensitive credentials like passwords. OAuth2 issues access tokens after successful authentication, which are then used to interact with secured resources. This protocol allows granular control over resource access based on scopes and roles. The article also introduces key OAuth2 concepts, such as the client, which is the application needing access, and the resource owner, who is the user that owns the data.
