Place the Iron Cage block to instantly construct a large 8x8x8 iron cage structure around that location. Upon placement, you will be prompted to type a password in chat, which is stored privately and required for anyone else to enter. As the owner, simply right-click the cage to open or close the door; non-owners must right-click and then type the correct password in chat to gain access, with the door automatically closing again after 10 seconds.
