This article is meant for developers or solution architects who want to integrate an Identity Server in their application.
Keycloak is an open-source Identity Server and Access Management Solution that provides user federation, strong authentication, user management, fine-grained authorization, and more.
Nowadays, a lot of Web APIs need the best security solutions and architecture to survive in this industry. The main reasons why developers may want to use a dedicated Identity Server are because it has built-in secure services, and the integration can be done with minimum effort.
Also, there is no need to deal with managing the users or the authentication and authorization processes. Since an Identity Server has built-in standard protocols, like OpenID Connect, OAuth2, and SAML2.0, developers will have a more secure API.
