Limited Login offers a login path that implements steps designed to prevent the fact that a person used Facebook to log in to your app from being used to target advertising or measure advertising effectiveness.
Limited Login returns an
AuthenticationToken that wraps an OpenID Connect token. The ID token cannot be used to request additional data using the Graph API, such as friends, photos, or pages. Doing so requires the use of classic Facebook Login.
A successful login populates a global
AuthenticationToken instance. You can provide a nonce for the login attempt that will be reflected in the return token. In addition, Limited Login populates a shared profile instance that contains the basic information including ID, name, profile picture, and email (if granted by the user).
