Cyber Security Basics: Protect Passwords

password entry field

Why should you protect passwords? Because passwords can be used to:

  • Gain access to your computer and to data on it.
  • Authorize transactions without your knowledge.
  • Access programs, files and applications that only you and/or a selected group of others should have access to.
  • Change passwords and lock you out of your own accounts.

Use passwords that can't be easily guessed, and protect your passwords. Characteristics of good passwords:

  • At least 8 characters in length
  • Contain a mixture of upper and lower case letters, numbers, and symbols
  • Difficult to guess, e.g. don't include real words (English or otherwise) or personal information such as user/login name, names of family members, places, pets, birthdays, addresses, hobbies, etc.
  • Easy to remember (so you don't have to write them down)

Protect your passwords

  • Don't share or publish your password - protect it the same as you would the key to your residence. After all, it is a "key" to your identity.
  • Avoid writing your passwords down.
    • If you need to write your password down on paper, safeguard the paper in a locked drawer or cabinet rather than posted on your monitor, under your keyboard, or in a drawer near your computer!
    • Better yet, use a phrase to help you remember your password, such as: MdHF&NAW! (My dog Has Fleas and Needs A Wash!)
  • For additional information and tips, see the UCSC's Password Strength and Security Standards.
