There are a number of steps you have to complete to be able to login to Facebook. First, go to the `Identity Providers` left menu item
2016-05-26 19:09:17 +00:00
and selected `Facebook` from the `Add provider` drop down list. This will bring you to the `Add identity provider` page.

You can't click save yet, as you'll need to obtain a `Client ID` and `Client Secret` from Facebook. One piece of data you'll need from this
page is the `Redirect URI`. You'll have to provide that to Facebook when you register {{book.project.name}} as a client there, so
copy this URI to your clipboard.

To enable login with Facebook you first have to create a project and a client in the https://developers.facebook.com/[Facebook Developer Console].

NOTE: Facebook often changes the look and feel of the Facebook Developer Console, so these directions might not always be up to date and the
configuration steps might be slightly different.

You will need also to obtain the App ID and App Secret from this page so you can enter them into the {{book.project.name}} `Add identity provider` page.
Go back to {{book.project.name}} and specify those items and finally save your Facebook Identity Provider.
One config option to note on the `Add identity provider` page for Facebook is the `Default Scopes` field.
This field allows you to manually specify the scopes that users must authorize when authenticating with this provider.
For a complete list of scopes, please take a look at https://developers.facebook.com/docs/graph-api. By default, {{book.project.name}}
uses the following scopes: `email`.
