500 Most Common Passwords

I came across a list of the 500 most common passwords (originally from http://www.whatsmypass.com/?p=415 and from Perfect Passwords by Mark Burnett). I’ve de-HTMLized the list and its now available in text format for easy parsing. It will also be included as a plug-in for Yasca, my source code analyzer.

The ten most common passwords from the list are:

  • 123456
  • password
  • 12345678
  • 1234
  • (a type of feline / female body part)
  • 12345
  • dragon
  • qwerty
  • 696969
  • mustang

A recent post at Acunetix shows statistics on 10,000 recently leaked Hotmail passwords. The ten most common passwords on that list are:

  • 123456 (0.6%)
  • 123456789 (0.17%)
  • alejandra (0.10%)
  • 111111 (0.10%)
  • alberto (0.09%)
  • tequiero (0.09%)
  • alejandro (0.09%)
  • 12345678 (0.09%)
  • 1234567 (0.08%)
  • estrella (0.07%)

More information is available in this blog article.
