identity provider (IdP)First introduced in SAML specifications, an identity provider is the service that is responsible for authenticating users in a single sign-on operation. It is also responsible for providing user identifiers and other user information to the external service that the user wishes to use. An OpenID Provider (OP) is an identity provider. In all SSO flows, your system is the identity provider.
OpenID Provider (OP)An identity provider that provides identities using the OpenID Connect standard. Specifically, an OAuth 2.0 Authorization Server that is capable of authenticating an end-user and providing claims to a relying party about the authentication event and the end-user.
Relying Party (RP)An OAuth 2.0 client application that requires end-user authentication and claims from an OpenID Provider. If you are using OpenID Connect to enable your users to single sign-on to Brazen, Brazen is the relying party.
service provider (SP)This term refers an application or system that provides a service to a user. In most cases, the service provider relies on the IdP to assert the user's identity before creating an identity for the user in the service. An OpenID term Relying Party (RP) is synonymous with the service provider. In all SSO flows, Brazen is the service provider.
