What do you use online maps for? But of course as passwords!

Strange but true.  Bill Cheswick, a computer scientist at AT&T research, came up with this novel idea on how to use a latitude and longitude as an access code. And no, you don’t have to actually remember the numbers. All you need to do is go to the map, zoom to an area to a larger scale (street level) and click on to a point. And this is your password!

The key idea is that you have a data set with very deep data, and you have to drill down. You could drill down on a map of anything. Probably better if it’s a map of someplace you’ve never been, so you’re not tempted to pick your childhood home. You could have a 10 digit latitude, and a 10-digit longitude, then you have a 20-digit password.
