Remember the massive Yahoo data breach from earlier this year? Researchers from Lancaster University and China’s Peking University and Fujian Normal University created an algorithm to guess the passwords from the leaked list–and had a 73 percent success rate. After analyzing the leaked data, they revealed the top 10 most popular passwords used to protect Yahoo accounts.

Introducing the top 10 passwords you should never, ever use:

  1. 123456
  2. password
  3. welcome
  4. ninja
  5. abc123
  6. 123456789
  7. 12345678
  8. sunshine
  9. princess
  10. qwerty

The data resembles a similar finding from SplashData’s 2015 report of stolen passwords, which found that “123456” is still the most commonly used password, followed by “password,” and “12345678.”

If you, a family member, co-worker, or anyone you know still uses one of the passwords on this list, here’s what to do:


That goes without saying, but if your passwords haven’t been changed in the last 3 months, take an hour or so out of your day to create long and strong passwords for each and every one of your accounts. Here are some additional tips to help you create (and remember) your new, strong password:

  1. Stop using passwords containing dictionary words, slang, curse words, email addresses, names, places, etc. This can leave you susceptible to dictionary attacks, brute force attacks, and other sophisticated cyber threats.
  2. Get creative and start using different letters, numbers, and special symbols that you’ve never used before. Instead of changing an “s” to “$”, try to use a set of symbols that aren’t commonly used: ~ ` % & * # = +
  3. Use this password mnemonics trick to help you create a strong password you’ll remember. See this blog post for more details on this helpful life hack.
