Security clearance
From Memory Alpha, the free Star Trek reference.
Security clearance or security verification is a level of authority given to an officer based on rank, status and position. Computers then identify the individuals by the entry of their vocal or numerical authorization code. Alternatively, specially programmed isolinear rods entered into the computer can also allow various levels of security clearance. (DS9: "Babel", "The Passenger", "Vortex")
