pass-gen is a command-line utility that generates secure, pronounceable passphrases which can be used on their own, copied to a GUI password manager, or piped directly into a password manager.
Imagine you need to log into your email account from a computer at the library. Which password would you rather type in:
livable?DINGBAT?507? What if I told you that the second one is just as secure as the first?
