Red Mansard Escape

Jack and Joe were playing outside the house in which, for a long time no one lived. They decided to go inside and explore the house. When they reached the top, we saw an open door. The room was red and so interested friends, they instantly ran there. When they entered, the door was closed. They wanted to open it, but there was no door handle, and the door was only a compartment for a password. We need to find it!
