API login and JWT token generation using Keycloak
Red Hat single sign-on (SSO)—or its open source version, Keycloak—is one of the leading products for web SSO capabilities, and is based on popular standards such as Security Assertion Markup Language (SAML) 2.0, OpenID Connect, and OAuth 2.0. One of Red Hat SSO’s strongest features is that we can access Keycloak directly in many ways, whether through a simple HTML login form, or an API call. In the following scenario, we will generate a JWT token and then validate it. Everything will be done using API calls, so Keycloak’s UI is not exposed to the public directly.
