What are the authentication codes in the underground on your home site?
The underground terminal passcode is a simple "figure it out" puzzle. Pick any name, PAUL for example - and if it's wrong, one letter in that name is in the passcode (P or A or U or L). Pick another name, JEFF, one letter is also shared in the passcode (J, E, or F). Now by the third or fourth try, you should have an idea which correct passcode has one letter from each wrong answer before. PETER would have the P from PAUL and E from JEFF - for a correct passcode example.
