Password Tip of the Day: If you take the most common password in the world and put a '1' on the end of it, it doesn't suddenly become a good password.

That said, apparently MySpace users are doing better in the password protection arena than corporate computer users. From Bruce Schneier:

While 65 percent of passwords [from MySpace group] contain eight characters or less, 17 percent are made up of six characters or less. The average password is eight characters long.

...

Character Mix: While 81 percent of passwords are alphanumeric, 28 percent are just lowercase letters plus a single final digit -- and two-thirds of those have the single digit 1. Only 3.8 percent of passwords are a single dictionary word, and another 12 percent are a single dictionary word plus a final digit -- once again, two-thirds of the time that digit is 1.

...

Another password study (.pdf) in November looked at 200 corporate employee passwords: 20 percent letters only, 78 percent alphanumeric, 2.1 percent with non-alphanumeric characters, and a 7.8-character average length. Better than 15 years ago, but not as good as MySpace users. Kids really are the future.
