Schneier on Security: Choosing Secure Passwords

Most people think their passwords are secure.  Bruce Schneier thinks otherwise and writes a very compelling piece:

"Ever since I wrote about the 34,000 MySpace passwords I analyzed, people have been asking how to choose secure passwords.
My piece aside, there's been a lot written on this topic over the years -- both serious and humorous -- but most of it seems to be based on anecdotal suggestions rather than actual analytic evidence. What follows is some serious advice."
