This site ☛ http://howsecureismypassword.net/  will tell you how secure your password is.  Don't type in you're real passwords!!!  But it is fun to try out.... I use 1password from 1Password from Agile Web Solutions to generate my passwords.  I had it generate one that I wouldn't use and plugged it in... Seems like 39 billion years would mean it's a pretty good password...
