* `scope`: A comma-separated list of permissions you want to request from the user. See the Facebook docs for a full list of available permissions: http://developers.facebook.com/docs/reference/api/permissions. Default: `email`
* `display`: The display context to show the authentication page. Options are: `page`, `popup`, `iframe`, `touch` and `wap`. Read the Facebook docs for more details: http://developers.facebook.com/docs/reference/dialogs#display. Default: `page`
