See how real-world organizations like Red Hat, Siemens, CERN, European Union institutions, and Novartis deploy Keycloak for free, open source sso, mfa, oauth2, admin console, and scalable microservices.
Keycloak enables enterprise authentication by issuing a JWT-like token to your app, enabling federation with external identity providers like Google, Microsoft, or LDAP for single sign-on.
Download Keycloak from the official website and run it from the bin folder. Start in development mode, create an admin user, and access admin console to manage realms and users.
Explore the Keycloak dashboard, manage realms, clients, and users, and configure authentication options, identity providers, and user federation with LDAP or AD.
Create a realm named Coding Center, then configure a Spring Boot app as a Keycloak client with OpenID Connect, enabling redirect-based authentication and authorization code flow.
Configure the keycloak configuration file for production, moving from development mode to a production-ready server and opting for Postgre or other databases.
Download PostgreSQL from the official site for your OS, install with PgAdmin 4 to view database structures, and prepare for configuring it with Keycloak.
Generate a Spring Boot project via Spring Initializr with Maven, Java 21, including Spring Web and Spring Security, then set up a resource server to validate JWTs.
Configure a Spring security class to enable web and method security, wire a JWT converter, and enforce manager and employee roles on protected endpoints while permitting public APIs via Keycloak.
Do you want to master modern application security and protect your Java/Spring Boot applications like a pro? This course will teach you everything you need to know about Keycloak, the most popular open-source Identity and Access Management (IAM) solution.
In this hands-on course, you’ll start by learning the fundamentals of Keycloak—realms, clients, users, roles, and groups. Then, you’ll integrate Keycloak with Spring Boot applications to secure REST APIs, web apps, and microservices. Along the way, you’ll gain practical knowledge of OAuth2, OpenID Connect (OIDC), JWT tokens, and Spring Security, all while applying them in real-world projects.
Here’s what you’ll learn in this course:
Keycloak basics: setup, configuration, and core concepts.
Integrating Keycloak with Spring Boot & Spring Security.
Securing REST APIs with OAuth2 and JWT tokens.
Implementing role-based and fine-grained access control.
Enabling Single Sign-On (SSO) and identity federation.
Best practices for securing enterprise and microservice applications.
No prior Keycloak experience is required! A basic understanding of Java and Spring Boot will help you follow along.
By the end of this course, you’ll be confident in building secure applications with Keycloak and Spring Boot, making you highly valuable in today’s job market where application security, SSO, and microservice protection are in demand.
