Keycloak is an open-source product developed by the RedHat Community which provides identity and access management solutions to modern applications. It requires little to no code to secure your applications and services.

What you’ll learn from this tutorial:

  • Key concepts and benefits of Keycloak
  • How to secure a Spring Boot application with Keycloak

I’m planning to create a second part of this tutorial where we’ll cover Spring Security and third-party Social Media Identity Providers such as Google, GitHub, etc.

Let’s get started!

Overview of Keycloak

The key benefit of Keycloak is that it provides a Single-Sign-On (SSO) which makes it easier for users to access different applications. It’s a friendly approach for both users and developers.

As a developer, you don’t have to worry about implementing login forms or storing credentials in a database. As a user, you don’t have to remember various passwords to login to each application.
