It's certainly inconvenient if your password is hacked and your identity stolen. But if the CIA's password is hacked, it may mean a death sentence for its covert operatives.
Recently, there was a huge setback for the CIA when its spies in Iran and Lebanon were caught because their password was cracked. What was that password? PIZZA:
In Beirut, two Hezbollah double agents pretended to go to work for the CIA. Hezbollah then learned of the restaurant where multiple CIA officers were meeting with several agents, according to the four current and former officials briefed on the case. The CIA used the codeword "PIZZA" when discussing where to meet with the agents, according to U.S. officials. Two former officials describe the location as a Beirut Pizza Hut. A current US official denied that CIA officers met their agents at Pizza Hut.
From there, Hezbollah's internal security arm identified at least a dozen informants, and the identities of several CIA case officers.
