Authenticate(callback: Action<bool>): void;
void Authenticate(Action<bool> callback);
def Authenticate(callback as Action<bool>) as void
Description

Authenticate the local user to the current active Social API implementation and fetch his profile data.

This should be done before any other calls into the API. Depending on the platform this might trigger a blocking dialog for providing login details.
// JavaScript

                "\nIsUnderage: " + Social.localUser.underage;
            Debug.Log (userInfo);
