Service providers

A Service Provider (SP) is a website that users visit, that uses a separate Identity Provider (IdP) to authenticate users.

Flask SAML2 provides all of the functionality required to implement your own SP that can authenticate using one or more external IdPs. These IdPs can be written using flask_saml2.idp, or come from external providers.

The method ServiceProvider.create_blueprint() generates a Flask Blueprint, which needs to be registered in your application via app.register_blueprint(sp.create_blueprint()).

Any Identity Providers the SP can authenticate with need to be registered as well. These will be instances of IdPHandler.

An functional example SP and Flask application can be found in the examples/ directory of the repository.
