The correct code that opens the secret passage for you in the boss’s office is 2845. While there are no indications of the code in the room, the narrator will say the code a couple of times if you hear it while looking around. . While the code is the only way to open the passage yourself, if you just sit and wait without entering anything, Narrator will eventually tire of it and open it itself.
While 2845 is the correct code, Narrator doesn’t let you go right away if you enter it too early. Instead, they play relaxing music to calm you down before you open it. After interacting with this room a few times, the Storyteller will open the passage as you enter so you don’t have to wait here constantly.
