# OIDC Token for Limited Login



A successful login in Limited Login populates a global `AuthenticationToken` instance. You can provide a nonce for the login attempt that will be reflected in the return token and that your app can use to [validate the token](https://developers.facebook.com/documentation/facebook-login/ios/limited-login/token/validating). 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).

`AuthenticationToken` offers a set of endpoints for obtaining information about the implementation and for uninstalling the user from the app.
