[keycloak-dev] Identity first login flow

Hello Keycloak community, I am looking for more information on an custom authentication method named Identity first login flow. I found this concept in a keycloak Jira ticket https://issues.jboss.org/browse/KEYCLOAK-1514 The issue was opened 03/Jul/15. There was a discussion back in February of 2018 that mentioned that this functionality would be offered "out of the box", but i cant find any more mention of it, and the issue was just recently put into plan on 06/Mar/19 . In the description of Identity first login flow : "This makes it possible to not require a password for a user when other authentication mechanisms are used (for example fingerprint, two-way ssl, etc.). Also, it allows automatically redirecting to an external IdP when the user is linked to an external IdP (either the user used the IdP to login before or a email domain has been configured to the IdP)." Does anyone have any more information about this concept, an example of it working, or advice on how this login flow could be achieved? I have started looking into a custom authenticator and authentication flow, but it would be ideal if this functionality was built in. Thank you, Arlen <http://www.datastax.com/>
