Under which scenario Web Server flow will be used?

An Architect needs to set up a Facebook Authentication provider as a login option for a Salesforce Customer Community.
What portion of the authentication provider setup associates a Facebook user with a Salesforce user?

Universal Containers (UC) has a mobile application for its employees that uses data from Salesforce as well as uses Salesforce for authentication purposes. UC wants its mobile users to only enter their credentials the first time they run the app. The application has been live for a little over 6 months, and all of the users who were a part of the initial launch are complaining that they have to re-authenticate. UC has also recently changed the URI Scheme associated with the mobile app.
What should the Architect at UC first investigate?

Universal Containers (UC) is building a customer community and will allow customers to authenticate using Facebook credentials.

Universal Containers (UC) uses Global Shipping (GS) as one of their shipping vendors. Regional leads of GS need access to UC's Salesforce instance for reporting damage of goods using Cases. The regional leads also need access to dashboards to keep track of regional shipping KPIs. UC internally uses a third-party cloud analytics tool for capacity planning and UC decided to provide access to this tool to a subset of GS employees.

To access the analytics tool, UC IT has set up Salesforce as the Identity provider for Internal users and would like to follow the same approach for the GS users as well.
