Command transfer

The use of an authorization code to transfer command of a starship from one captain to another

The command authorization code (or simply authorization code) was an alphanumeric sequence used by militaries and civilian agencies to allow access to certain command protocols and restricted information. These codes were also known as a voice authorization code, security code, command code, access code, or simply password.

Some of the many uses of authorization codes including: activating and canceling auto-destruct sequences, transferring of command of a starship, accessing secured locations, and ejecting a warp core. (Star Trek: First Contact; VOY: "Deadlock", "Dreadnought", "Cathexis", "Renaissance Man"; TNG: "Chain of Command, Part I")


In Starfleet, the style of code varies from decade to decade. In 2365, the code was a long sequence of numbers, letters from the Human Greek and English alphabet pronounced phonetically and colors. By the following year, the code standardized to a form used from that point on. Typically, this would involve the user's name, Greek letters, and numbers. Codes are changed on a regular basis, to prevent sabotage and security breaches.

Doctor Kila Marr isolated the access code of the science station on the bridge of the USS Enterprise-D thereby making it impossible to turn off the graviton pulse that was destroying the Crystalline Entity. (TNG: "Silicon Avatar")

Examples aboard USS Enterprise-D and -E

Examples aboard Deep Space 9 and USS Defiant

Aboard Deep Space 9 and USS Defiant, authorization codes optionally included an action word related to the request being made.

Examples aboard USS Voyager

Aboard the USS Voyager, authorization codes optionally included colors and clearance levels.

Other examples


The storage lockers in the assay office aboard Deep Space 9 were secured by personal authorization codes. (DS9: "Q-Less")


Cardassian authorization codes are somewhat customizable in that high-ranking officers can add additional security checks to restrict use of their security clearances.

S.G. Dukat added several such subroutines to his counter-insurgency program aboard Terok Nor; when Elim Garak attempted to imitate Dukat to shut down the program, it constantly challenged Garak to prove his identity. When Dukat later attempted to beam back to his ship while the program was running, however, he discovered one of his superiors had altered the program to prevent Dukat from escaping in the event of a Bajoran revolt. (DS9: "Civil Defense")


In order to access communications aboard D'Kora-class, the DaiMon's authorization was required for all transmissions. The access code of DaiMon Tog, the commander of the Krayton, was (in part) "Keh-ee Yoor-ee Dah-teh-ee..." (TNG: "Ménage à Troi")


A defense access code was a message that, when transmitted, caused the defensive systems of the Khitomer outpost to become inoperative. (TNG: "Sins of the Father")

Authorization code bypass

In 2372 Neelix was able to gain access to Tom Paris's computer with an engineering authorization code (Engineering-Authorization-Omega-4-7) without the proper voiceprint of Paris. (VOY: "Investigations")
