Get the Admin Password Walkthrough
With that new information in mind, its time to follow the quest marker to the ground floor of one of the hotel buildings and find Vincent Fried’s Terminal. The terminal is located behind one oof the desks, and there is actually a chance for a Bobblehead to spawn underneath it so be sure to check the shelf. Inside the terminal select “Inbox” then “Admin Password“. This will tell you where to find the password, located at another location called the Palace of the Winding Path. The palace is a massive location full of loot, Super Mutants, and Scorched, so be sure to loot to your hearts desire (and use the benches in the basement to scrap).
Once you are done grabbing the goods, follow the quest marker to the librarians room and grab the password out of the secret compartment in his dresser. Take that password to the Holotape Duplication Terminal denoted by the quest marker, then select options Duplicate From Archives then Diehard’s Key Fragment to get the next piece of the key.
