Pro tip: choosing “password” as your online password is not a good idea. In fact, unless you’re hoping to be an easy target for hackers, it’s the worst password you can possibly choose.

“Password” ranks first on password management application provider SplashData’s annual list of worst internet passwords, which are ordered by how common they are. (“Passw0rd,” with a numeral zero, isn’t much smarter, ranking 18th on the list.)

The list is somewhat predictable: Sequences of adjacent numbers or letters on the keyboard, such as “qwerty” and “123456,” and popular names, such as “ashley” and “michael,” all are common choices. Other common choices, such as “monkey” and “shadow,” are harder to explain.

As some websites have begun to require passwords to include both numbers and letters, it makes sense varied choices, such as “abc123″ and “trustno1,” are popular choices.

SplashData created the rankings based on millions of stolen passwords posted online by hackers. Here is the complete list:

SplashData CEO Morgan Slain urges businesses and consumers using any password on the list to change them immediately.

“Hackers can easily break into many accounts just by repeatedly trying common passwords,” Slain says. “Even though people are encouraged to select secure, strong passwords, many people continue to choose weak, easy-to-guess ones, placing themselves at risk from fraud and identity theft.”
