User Management
At the core of many apps, there is a notion of user account management that lets users access their information in a secure manner. A specialized user class called
ParseUser is available to automatically handles these kind of functionalities.ParseUser is a subclass of the ParseObject, and has all the same features. All the methods that are on ParseObject also exist in ParseUser. The difference is that ParseUser has some special additions specific to user accounts.Signing Up
