The world's worst "password" has finally been dethroned.

The term, widely considered by security experts as one of the more frequently used--and most susceptible to hack attempts--passwords has been replaced by "123456", according to PCWorld.

The list of dubious passwords also included gems like "qwerty", "abc123" and "letmein".

Password security has taken on increasing importance in a world where hacking and identity theft has become more commonplace. Weak passwords are more vulnerable to what PCWorld called "brute force attacks."
