Well Assuming that these kids have all read the last book, why don't you make the passwords the names of the horcruxes for each house? So Slytherin would be locket, Hufflepuff would be cup, and Ravenclaw would be diadem, Gryffindor would be sword (I know it didn't end up being a horcrux but LV wanted it to be). Then its nice and easy and you can give them the clue and they can figure out the password!
