Common Passwords

Security companies sometimes get to analyse real people’s passwords and create interesting reports. Imperva has just done that, analysing 32 million passwords used on the site (which was recently hacked).

Below is a summary of their findings. Why is this important to you? Because it means that statistically, you probably have a weak password that can be guessed.

  • 41% of passwords only use lower case letters (weak)
  • 15% of passwords only user numerals (even weaker)
  • Nearly 50% of people used names, slang words, dictionary words or trivial words as their passwords. These can be guessed in seconds by a “brute force” program.

The ten most common passwords were:

  1. 123456
  2. 12345
  3. 123456789
  4. Password
  5. iloveyou
  6. princess
  7. rockyou
  8. 1234567
  9. 12345678
  10. abc123

If you use any of these as your password then change it now, it’s too easy to guess, especially now that everyone can see this list.
