Hi folks, I’m new to Keyclaok and also OIDC protocols. I’ve successfully built a Spring Boot application with Keycloak, and I created one realm and one client there. I could also get JWT of the client with client-secret. However, this practice is client-base and what I want to do is getting JWT by each user. Suppose I have… RealmA - ClientA: UserA, UserB… - ClientB: UserC, UserD… Is there way that I can get JWT of UserA to UserD with OIDC way? I’ve found it can be implemented using id-password base though, should I need to use login way if I want to make it user-base or is there any other way to fulfil it using OIDC? Thanks ---

There is no direct link between the client and the user. This means that the user attempts to log in to an app related to a client that implements one of the OIDC standards (usually Authorization Code or Authorization Code + PKCE) with your IdP. Therefore, based on your example, Users A, B, C, and D can log in to AppA (ClientA) or AppB (ClientB) without any issues. In Spring Boot, you can easily use the `spring-boot-starter-oauth2-client`. ---
