IdP (Identity Provider)


A system that creates, maintains, and manages identity information.

IdP (Identity Provider), is a system that creates, maintains, and manages identity information for principals (users, services, or systems) and provides principal authentication to other service providers (applications) within a federation or distributed network. It is a trusted third party that can be relied upon by users and servers when users and servers are establishing a dialog that must be authenticated. The IdP sends an attribute assertion containing trusted information about the user to the SP.
