“123456” Still Most Used Password

worst password

For two years in a row, “123456” remains the worst password because it is the top password among millions exposed online thanks to data breach incidents at various providers.

While having “123456” as your password is very bad, the other terms found on a list of  “Top 100 Worst Passwords of 2017” are just as confusing and regretful.

Some of these include a collection of sports terms (football, baseball, soccer, hockey, Lakers, jordan, golfer, Rangers, Yankees), car brands (Mercedes, Corvette, Ferrari, Harley), and various expressions (iloveyou, letmein, whatever, blahblah).

But, by far, the list was dominated by names, with the likes of Robert (#31), Matthew (#32), Jordan (#33), Daniel (#35), Andrew (#36), Andrea (#38), Joshua (#40), George (#48), Nicole (#53), Hunter (#54), Chelsea (#62), Phoenix (#66), Amanda (#67), Ashley (#69), Jessica (#74), Jennifer (#76), Michelle (#81), William (#86), Maggie (#92), Charlie (#95), and Martin (#96), showing up on the list.

The list was put together by SplashData, a company that provides various password management utilities such as TeamsID and Gpass. The company said it compiled the list by analyzing over five million user records leaked online in 2017 and that also contained password information.

“Use of any of the passwords on this list would put users at grave risk for identity theft,” said a SplashData spokesperson in a press release that accompanied a two page PDF document containing a list of the most encountered passwords.

This is because attackers use these same leaked records to build similar lists of leaked passwords, which they then compile as “dictionaries” for carrying out account brute force attacks.

Attackers will use the leaked terms, but they will also create common variations on these words using simple algorithms. This means that by adding “1” or any other character combinations at the start or end of basic terms, users are not improving the security of their password.

Advising users on best password policies is a doctoral paper in its own right, but for the time being, users should look into using unique passwords per account, possibly employing a password manager, using more complex passwords, and above all, staying away from the terms below.
