Identity Provider Metadata
IDP metadata refers to information that describes an Identity Provider (IDP) and its configurations, such as Entity ID, Single Sign-On Service URL, and certificate information. This metadata is used by Service Providers (SPs) to configure their trust relationship with the IDP for secure authentication and authorization.
You can provide IDP metadata to Service Provider in 3 ways:
Using the Metadata URL.
Using the XML file.
By manually providing the information.
