When we migrate user to keycloak from external database, with User Storage Provider, we noticed that there is no password migrated to keycloak system from external system. That means that we could not get rid of the external system database, and make a switch to use migrated user data in keycloak. We would need to disturb a user to set a new password or something like that then. Is there a clear guide how we could migrate a user with its full credentials to keycloak, or is this not intended by keycloak design for this use case. If it is not intended by keycloak to be used like that, what would you suggest instead?
