 * `display`: The display context to show the authentication page. Options are: `page`, `popup` and `touch`. Read the Facebook docs for more details: https://developers.facebook.com/docs/reference/dialogs/oauth/. Default: `page`
+* `auth_type`: Optionally specifies the requested authentication features as a comma-separated list, as per https://developers.facebook.com/docs/authentication/reauthentication/.
