Access Token Guide - Facebook Login - Facebook for Developers
Access Tokens. An access token is an opaque string that identifies a user, app, or Page and can be used by the app to make graph API calls. When someone connects with an app using Facebook Login and approves the request for permissions, the app obtains an access token that provides temporary, secure access to Facebook APIs.
