Re: [keycloak-user] Login without Keycloak Login Page

That's an extremely bad hack! The authorization code flow is a redirect based flow and should not be used in this way. Please use the real login page as recommended. Alternatively use resource owner password grant (direct grant in Keycloak). With direct grants you can only invalidate the refresh token, not the session or access token so you should have a short lifespan on your access tokens. On 21 December 2016 at 09:21, ruiwp13 <
