This challenge is part of the Skye’s Adventure Challenges, the fourth agent Fortnite Chapter 2 Season 2 focuses on. You'll have to escape from a vault using a secret passage, and first you'll have to go to one of the five bases that have one. To access these highly guarded rooms, you'll need to get rid of the agent who supervises the place — Brutus, Skye, Midas, Meowscles or TNTina. When you die, these agents will give you a map showing the exact location of the room — often in the basement — and allow you to access it by scanning it at the entrance.

Once inside, take the equipment you need and enter the blue toilet which turns out to be a secret passage to the exit. Be careful though: these places are very well guarded by henchmen and defensive turrets. Don't underestimate them.
Also note that these vaults are unavailable in Team Rumble.
