How to create a strong password

ALTA Best practices encourages the use of strong passwords for your computer systems. Passwords provide the first line of defense against unauthorized access to your computer. The stronger your password, the more protected your computer will be from hackers and malicious software. You should make sure you have strong passwords for all accounts on your computer. If you’re using a corporate network, your network administrator might require you to use a strong password.

What makes a password strong (or weak)?

A strong password:

  • Is at least eight characters long.

  • Does not contain your user name, real name, or company name.

  • Does not contain a complete word.

  • Is significantly different from previous passwords.

  • Contains Uppercase letters, Lowercase letters, numbers and symbols

A password might meet all the criteria above and still be a weak password. For example, No1password! meets all the criteria for a strong password listed above, but is still weak because it contains a complete word. N01 p@ssw0rd! is a stronger alternative because it replaces some of the letters in the complete word with numbers and also includes spaces.

Help yourself remember your strong password by following these tips:

  • Create an acronym from an easy-to-remember piece of information. For example, pick a phrase that is meaningful to you, such as My daughter’s birthday is 28 October, 1974. Using that phrase as your guide, you might use Mdbi28/Oct,74 for your password.

  • Substitute numbers, symbols, and misspellings for letters or words in an easy-to-remember phrase. For example, My daughter’s birthday is 28 October, 1974 could become MiDauBrthd8iz 281074 (it’s OK to use spaces in your password).

  • Relate your password to a favorite hobby or sport. For example, I love to play basketball could become ILuv2PlayB@sk3tb@ll.

If you feel you must write down your password in order to remember it, make sure you don’t label it as your password, and keep it in a safe place.
