OAuth 2.0 is an open standard for authorization that is commonly used to authenticate and authorize access to resources in a Spring Boot application. It allows a user to grant a third-party application access to their resources, without having to share their login credentials.

Spring Boot provides a number of libraries and modules that make it easy to implement OAuth 2.0 in a Spring Boot application. One popular library is Spring Security OAuth, which provides a set of features for securing applications and services using OAuth 2.0.

To use Spring Security OAuth in a Spring Boot application, you need to add the Spring Security OAuth dependency to your project and configure it with the necessary details for the OAuth 2.0 provider you are using (such as Google, Facebook, or your own custom OAuth 2.0 provider).

Once you have configured Spring Security OAuth, you can use the @EnableOAuth2Sso annotation to enable OAuth 2.0 Single Sign-On (SSO) for your application. You can also use the @EnableOAuth2Client annotation to enable OAuth 2.0 client support, which allows your application to access resources protected by an OAuth 2.0 server.

In addition, Spring Security OAuth provides a number of classes and interfaces that you can use to customize the authentication and authorization process. This includes classes for handling authentication events, performing token validation, and handling token errors.

It's important to note that OAuth 2.0 is a complex standard and implementing it in a secure way is crucial. It is recommended to have a good understanding of the OAuth 2.0 standard before attempting to implement it in a production environment.
