What is Keycloak?

Keycloak is an open source identity and access management solution. Keycloak allows you to implement features such as single sign-on, multi-factor authentication, user management, and access privilege management. Keycloak is also used to provide secure authentication and authorization for various applications and services.

Keycloak is widely used in the identity and access management field. In particular, it is employed by businesses and organizations to implement secure authentication and authorization when developing web applications and microservices. Companies of all industries and sizes are deploying Keycloak to take advantage of features such as single sign-on and multi-factor authentication.

History of Keycloak

Keycloak was launched by Red Hat in 2014 and released as an open source identity and access management solution. Since then, it has undergone regular updates and continues to improve, including support for cloud-native applications and enhanced security.

Using Keycloak

1. Authentication for web and mobile applications

Keycloak makes it easy to implement Single Sign-On (SSO) which allows users to log in once to access multiple different applications, which not only improves user experience but also strengthens security.

2. Strengthening security for enterprise applications

Large companies and organizations have many internal applications and need to centrally manage their security. Keycloak makes it easy to implement unified authentication policies across these applications, greatly streamlining security management.

3. Providing social login

You can give them the option to log in using their existing social media accounts, such as Facebook or Google. This makes the registration process for new users easier and the login process smoother.

4. Implementing multi-factor authentication

For added security, Keycloak supports setting up two-step and multi-factor authentication. This allows you to require additional authentication methods, such as SMS or a token app, in addition to a password.

5. Security of Microservices and APIs

Keycloak is also suitable for managing authentication and access control between services in environments where microservices architectures and APIs are used. Enhance the security of your API and protect it from unauthorized access.

6. Customizable user management

Through the Keycloak Admin Console, administrators can perform a wide range of user management tasks, including managing user profiles, configuring role-based access control, and adjusting group membership.

As such, Keycloak is an extremely versatile and powerful tool that can address authentication and authorization needs in a wide variety of scenarios, from small to large environments.
