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:
Always
- 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.
Never do not
- 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.
