Journey

1. User navigates to Relying Party Web site, for this journey it is a patient viewing a patient portal. The patient portal may receive a cookie from a prior visit
2. RP displays one or more sign in options for the user (note that the patient view may be determined by the existence of a valid cookie)
3. The user clicks on one sign in option . At this point there is a fork in the journey based on the cookie.

Fork one: User is apparently new as there is no existing cookie (A registration journey)

1. Legacy journey would have the user sign into the portal using a local user name and password. That would be an and to the user journey.
2. User selects to use a federated sign in process. (Note that this process may be a related hospital group or some other federated idp.)
3. User browser receives an HTTP 302 redirect message and the dip sign in page is displayed.

5. Port of the IdP message to the user is a list of the attributes (claims) tnat will be passed from the dip to the patient portal.
6. The IdP issues a redirect to the user browser with shows the patient portal home page customized for that users.
7. The user may need to locate their patient records on the patient portal which may ask the user for additional attributes (claims).

2. A cookie is found which is expired or just has the user ID. The user is directed to a sign in Experience.
