A study reveals the list of worst passwords of 2019

Another year is ending and this is the right time to discover which are the worst passwords of 2019 by analyzing data leaked in various data breaches.

Independent anonymous researchers, compiled and shared with security firm NordPass a list of 200 most popular passwords that were leaked in data breaches during 2019. The company collected 500 million passwords in total and the results were disconcerting.

Over 2019, security experts reported several data breaches that affected billions of internet users, for example, the popular Collections #1-5 alone contained exposed 3 billion records. With data breaches becoming so commonplace, internet users need to step up their cybersecurity game.

The research conducted by NordPass revealed that bad habits continue to expose users to the risk of hack, users continue adopting weak passwords because they are easier to remember, and share them among multiple services online.

“The most popular passwords contain all the obvious and easy to guess number combinations (12345,111111,123321), popular female names (Nicole, Jessica, Hannah), and just strings of letters forming a horizontal or vertical line on a QWERTY keyboard (asdfghjkl, qazwsx, 1qaz2wsx, etc.). Surprisingly, the most obvious one — “password” — remains very popular; 830,846 people still use it.” reads the post published by NordPass.

Experts found that ‘12345’, ‘123456’ and ‘123456789’ are the most popular passwords, followed by ‘test1’ and, the ‘password’.

Other easy to predict common passwords are simple strings as ‘asdf’, ‘qwerty’, ‘iloveyou,’ along with simple numerical strings and common names. The data are quite identical to the ones reported in the studies on the worst passwords conducted by SplashData in the last years.

Below the Top25 list of the 200 most popular passwords shared by the experts:

  5. Be vigilant for suspicious activities and if you notice something unusual, change your password immediately.
