The method and apparatus for sharing passwords includes an electronic meter comprising a metering unit, a register unit, an optical port, and a communications unit. An external reading device, such as a handheld reading device or a personal computer, is coupled to the communication board via the optical port. The method and apparatus for sharing passwords provides that both the meter register and the communications unit have the same security code. In addition, the communications unit is able to distinguish between a security code for the communications unit and a security code for the meter register, and the communications unit will not interfere with communications between the external reading device and the meter register.
