From top to bottom is, Thief's Downfall, which takes away all disguises (Polyjuice Potion, Invisibility Cloak... etc.), a blinded dragon, and a door that sucks people inside. Not goblins. If you happen to own a special vault, they can make it so no ghosts can pass through the doors and walls, place a gemino curse on it (anything you touch will duplicate itself) and have a key for certain items.
she has no particular intention yet, but she said that she wanted to "keep the doors open" in case she ever wants to write something in the harry potter world again.
Look through secret doors or find some on your own?
The spell that opens a locked door is "Alohomora!" The spell is taught during the first year of education at Hogwarts. The first book in the Harry Potter series -- Harry Potter and the Sorcerer's Stone -- chronicles Harry's first year. "Alohomora" is a charm and thus would've been taught by Filius Flitwick during Harry Potter's time at Hogwarts.
Hagrid' Hut is a location in Harry Potter in games 5 and 6, but you cannot go in. In order to keep the development costs and game size reasonable for all platforms, there needs to be doors in Hogwarts that are always locked. If the game developers spent more money on the platforms such are the PS3 which have a much higher capacity optical disc, it might have been possible to allow the player to open these doors.
