xkcd’s advice on creating memorable passwords

xkcd comic offers some helpful advice on creating memorable but still difficult to hack/guess passwords.

 

“Through 20 years of effort, we’ve successfully trained everyone to use passwords that are hard for humans to remember, but easy for computers to guess.”

Take a lesson: a password of four random words is harder to guess but easier to remember than a one-word password containing some gibberish symbols substituting for letters.
