It probably depends on how many IdP's you want to support. If you only have one, you
can enable the setting in the IdP configuration for 'Authenticate by Default'.
This will bypass the local login.
You'll need to modify / copy the first broker login auth flow to create the user upon
successful auth. Otherwise you'll get a failed login.
Probably doesn't answer all your questions but hope it helps.

Subject: [keycloak-user] Force Keycloak to use external IdP as authentication mechanism
We have a requirement to disable local login (username/password) and allow login through
IdPs configured in Identity broker.
To test this scenario I have configured Salesforce as SP and Keycloak as IDP. And in IdP
(keycloak) disabled "Forms" based login and configured an external IdP as
identity broker.
But this configuration resulting in "Invalid username or password." error in
keycloak. In logs I observed following stack trace.

Any idea how to disable the username/password prompt during the login and force keycloak
to use configured identity brokers?
Also, in case I have multiple external IdPs configured as identity brokers in my keycloak
instance is there any way to inform keycloak to use particular external IdP (broker). I
know we can use kc_idp_hint parameter.
This will be helpful during IdP initiated sso but in case it is a SP initiated SSO, how
can we specify the default external IdP?
Thanks!
