"""
Make a blueprint for authenticating with Okta using OAuth 2. This requires
a client ID and client secret from OKta. You should either pass them to
this constructor, or make sure that your Flask application config defines
them, using the variables OKTA_OAUTH_CLIENT_ID and OKTA_OAUTH_CLIENT_SECRET.
Args:
client_id (str): The client ID for your application on Okta.
client_secret (str): The client secret for your application on Okta
scope (list, optional): list of scopes (str) for the OAuth token
redirect_url (str): the URL to redirect to after the authentication
dance is complete
redirect_to (str): if ``redirect_url`` is not defined, the name of the
view to redirect to after the authentication dance is complete.
The actual URL will be determined by :func:`flask.url_for`
login_url (str, optional): the URL path for the ``login`` view.
Defaults to ``/okta``
authorized_url (str, optional): the URL path for the ``authorized`` view.
Defaults to ``/okta/authorized``.
session_class (class, optional): The class to use for creating a
Requests session. Defaults to
:class:`~flask_dance.consumer.requests.OAuth2Session`.
backend: A storage backend class, or an instance of a storage
backend class, to use for this blueprint. Defaults to
:class:`~flask_dance.consumer.backend.session.SessionBackend`.
:rtype: :class:`~flask_dance.consumer.OAuth2ConsumerBlueprint`
:returns: A :ref:`blueprint <flask:blueprints>` to attach to your Flask app.
