Authorization code

Alpha alpha one zero priority override was a type of special command officer override introduced in the novel The Romulan Prize. When the command officer invokes the override by calling out "Priority override, (name of command officer) alpha alpha one zero!" the computer will block invocation of the function being overridden, no matter the level of authorization of the command, render the authorization method useless, and any file information being accessed is erased. The override will also operate under vocal computer lockout conditions, even though it is vocal authorization.

In The Romulan Prize, the Romulan commander Valak attempted to use an isolinear chip with special encoded authorization that was obtained from Starfleet Command to look up information on Hermeticus II. Upon Captain Picard discovering that the isolinear chip gave Valak information on Hermeticus II, Picard shouted out "Priority override! Picard alpha alpha one zero!", ending the information readout, deleting the file, and voiding the isolinear chip (the Romulan guarding Picard clubbed him with his disruptor for his trouble though).
