WhatsMyPass has the grim details
Hint: repeating letters and numbers, using a simple keyboard pattern, or using “password” as a password is really, really dumb. No doubt many of these Worst Passwords are used by the clueless for banking sites too.
For important sites, mix the case, use numbers and special characters, and make it at least eight characters long.
(And don’t put them on a Post-It on your monitor either!)
