Claim 15:
16. An intelligent electronic device (IED), comprising:
a metering module configured for measuring or calculating parameters of waveforms of voltages and currents of an electrical power distribution system;
a processing module configured for processing data obtained using the metering module and administering operational features of the IED;
a communication module configured to transmit and receive data over at least one network; and
a user authentication module configured for authenticating an authorized user of the IED and preventing an access by non-authorized personnel to a portion of the operational features of the IED, the user authentication module including at least one input device disposed on the IED and configured to acquire a piece of user credentials,
wherein the user authentication module transmits the user credentials to at least one server via the communication module, the at least one server determines the authorized user based on the user credentials and a preselected mode of communication of the determined authorized user and transmits a code to at least one external device associated to the determined authorized user, and
upon receipt of the code from the determined authorized user at the user authentication module, the user authentication module verifies the received code and grants the authorized user access to the portion of the operational features of the IED for a pre-determined time interval.
