Enter the dungeon

You enter the next room and find it empty, you walk towards the door and try to open it. However the door is locked but there is a padlock holding the doors together. You try to break the padlock however the sword does nothing and you aren’t strong enough to pull the padlock off. You realise the padlock needs a four digit password to enter the final room
