[keycloak-user] SSO experience

[Ori Doolman]

Hi Dmitry,
Thank you for answering.
In fact, the desktop app is not yet integrated to Keycloak and it is work to be done. 
I'm not familiar with the desktop app since it is a 3rd party app not written by us. If Java based, I thought of using one of the Keycloak Java adapters. If not, just get the token with an HTTP[S] call (which seems that this is also what kcinit and KeycloakInstalled are doing as well).
I was not familiar with kcinit or KeycloakInstalled before. 
KeycloakInstalled might be a solution, but with limitations:
1) The desktop app must be written in Java.
2) It must be acceptable by the app designers to launch a browser for login. 
3) If I understand correctly, it only performs a client level authentication, not supporting username/password credentials authentication.

That leads me to the original question - can I have SSO without using cookies, and by simply send the token to my web app as part of the starting URL (the desktop app will launch the web app in a browser)?

Hello Ori,

How do you implement SSO for your desktop application? Are you using kcinit [1] or KeycloakInstalled [2]?

Both will do interactive login via the system browser, that means, SSO cookies should be shared with whatever web application that is run therein.
