If you have something physical of equivalent value to 100 million people's bank passwords, you may well not want to risk keeping it in a desk drawer at all, and instead want to look into renting a nice secure drawer from someone else to keep it in. That would be a safety deposit box. Which I would argue is rather more like what cloud providers offer than 'someone else's desk drawer' is.
