All of the following qualify as being bad ideas for a password:

  • Username in any form (as-is, reverse, k-rad'd, etc)
  • First or last name in any form (see above)
  • Spouse's, girl/boy friend's, pet's, or children's names
  • Any information readily available to the public (phone numbers, street name, license plate number, etc)
  • All the same of any character

Any password used as an example password in any book, magazine, web site, manual, etc.;

Any password in /usr/dict/words or in any printed dictionary in any language;

Any password without significant amounts of non-alphabetic characters like !@#$%^&*()-=\_+|{};':",./<>?
