The system reuses the classic User ID & Password combination for authentication and adds a third component called a USE code for additional authorization check, as an example. This method allows access to a system when it is requested with correct User ID and Password (i.e., with correct pass code) but with an unauthorized USE code, the system identifies it as an unauthorized access and triggers the proper security measures to minimize the damage and monitor the actions in a way not to alarm the unauthorized user who is using the owner's credential to access the system. The USE Code is an extension to the pass code to raise various alarms and have a stepwise access level control based on different inputted values.
