Questions tagged [objectid]

The ID of an object. This is used, among other reasons, to refer back to the object at a later time in the program

Used especially in web programming where space on the stack is limited, objectids are used to refer to objects at different parts of the program, and possibly even across different user sessions, if some marshalling is implemented (as databases, etc).

The ID of an object can also be used to determine if two objects are distinct instances or are indeed the same object, in which case, any modifications made on one would be reflected in the other as well

Parse.com security : Access object of another app if you know the objectId

Is it possible to get data of an object/user on Parse.com, if the objectId of the ParseObject is known? I want to know about it as a security concern, if it is possible for some other app to access objects from my app if the objectId is known?
