Thought I already answered this? It is possible to make keycloak login look entirely different. The login pages all use Freemarker templates and you have the ability to override anything you want piecemeal, or you can entirely change the look and feel. Here's a good example of that: https://developers.redhat.com/auth/realms/rhd/account Here's the documentation on themes: http://keycloak.github.io/docs/userguide/html/themes.html Now, can you make it look completely different for different apps? Our theme framework does not have this capability. But, the client making the call is available in the login.ftl template as a variable, you could have a bunch of #if statements everywhere. Would look really ugly and hard to maintain, but it would work.
