Password Strength

Password Strength

The strength or effectiveness of a password is determined by following factors:

  • its length
    (each additional character increases its usefulness several times)
  • its randomness
    (non-compliance with a dictionary or commonly known phrases)
  • type of characters used
    (letters, numbers, special characters)

This must be complemented by the efforts to keep the secrecy of the password, so:

  • use a different password than your login,
  • use a password longer than 8 characters (preferably 14),
  • complicate the password to make it "crazy" for the outsiders,
  • use not only letters, but also numbers and special characters as far as possible,
  • from time to time change or modify your passwords.
  • write your password on a piece of paper sticked to the monitor,
  • save passwords in a text file "my passwords" on the desktop,
  • create passwords based solely on one word familiar to you ("Katrin" [name of your daughter], "04111978" [your birthday], ...),
  • use obvious and easiest passwords ("qwe", "123456", "zbcdef", ...),
  • use the same password for different accounts,
  • use words from a dictionary (any language, including words spelled backwards, and typical spelling errors)
  • disclose your password or the method of their creation to anyone
  • give your password on request sent by e-mail,
  • use in your password information that someone could guess or get (name, date, license plates),
  • use computers you don't have full control of, to log on anywhere. Computers in cafes, at conferences, airports, even at friends homes, should be used only to browse the Internet.
