Correct horse battery staple

Correct horse battery staple is a 4-word phrase popularized by Randall Munroe of XKCD in XKCD 936 to demonstrate that passwords with random word combinations are more secure than those with various special characters, such as Tr0ub4dor&3, as well as being easier to remember. Due to the fame of the comic, this password is no longer secure, as it might be one of the first passwords a hacker will try.
