Everyone should know which passwords suck. Do you?

Everyone should know which passwords suck. Do you?

You probably already know that a password like 123456 is bad. It's so simple and predictable that even other humans can easily guess it. But do you know all the other passwords that are just as weak?

AI search analytics firm Peec AI recently looked at a small portion of stolen password data, dating from 2019 until now. And while its analysis yielded similar results to what security researchers have already uncovered (fave.co/3K42ZHn) from far larger amounts of data, the findings proved the point: People really suck at creating their own passwords.

In Peec AI's slim data set of about 100 million unique passwords, common themes we've seen time and time again popped up once more:

Simple number strings: 123456 is always a top weak password—about 6.6 million in this data slice. Trailing behind is 123456789 at 2.2 million, with 111111 coming in at almost 1 million.

Easily guessed: Password, qwerty, and abc123 all came close to a million uses each.

imageThis chart shows how fast a consumer-grade PC could crack a password. Dedicated hackers can choose to devote more resources to their efforts.
