Preface
Keycloak is an open source identity and access management tool with a focus on modern applications such as single-page applications, mobile applications, and REST APIs.
The project was started in 2014 with a strong focus on making it easier for developers to secure their applications. It has since grown into a well-established open source project with a strong community and user base. It is used in production for scenarios ranging from small websites with only a handful of users up to large enterprises with millions of users.
This book introduces you to Keycloak, covering how to install Keycloak as well as how to configure it ready for production use cases. Furthermore, this book covers how to secure your own applications, as well as providing a good foundation for understanding OAuth 2.0 and OpenID Connect.
