While I was stuck in traffic last night staring at license plates I thought of this post. This is a likely bad idea for a password scheme. Why? Because anyone who knows the scheme can more easily crack a password. If I know you will be using 0-9 in four places, and letters from a name for the rest, I know that if the name is Sam Jones there are only 17 (10 numbers 7 letters, since the s is repeated) possible characters per place, with only 4 of them being digits. So if the password was between 8 and N places, you can do the math to see the finite number of possabilites. And, as some of us know, people don't change easy to remember default passwords unless they are forced to :)

Cheers,
KM
