Strong passwords are the key to a safe digital life. May 6th is World Password Day so CDE Lightband has some do’s and don’ts for when it comes to choosing a secure password and keeping your data safe


  • Use a combination of uppercase and lowercase letters, symbols and numbers.
  • Make sure your passwords are at least 8 characters long.
    • The more characters you use, the more difficult they are to guess.
  • Change your passwords regularly.
    • It’s recommended that you change your passwords every three months.


  • Don’t use commonly used passwords such as 123456 or the word “password.”
  • Don’t use a derivative of your name or family members.
  • Don’t use your social security number.
  • Don’t use the same password across multiple websites.
  • Don’t write your passwords down or share them with anyone.
  • Don’t answer “yes” when asked to save your passwords on your browser.

This may seem like a complicated process but it’s not as complicated as what will happen if a cyber criminal gains access to your passwords and steals your identity.

How hackers work?

There are several ways hackers can crack passwords outside of spyware.

  • They can attempt to log on to your account by guessing your password based on personal information gained from your security questions.
  • They can use a password cracker that uses brute force by using multiple combinations of characters repeatedly until it gains access.
    • The shorter and less complex your password is, the quicker it can be for the program to come up with the correct combination of characters.
  • They can use a dictionary attack, where the program will cycle through a predefined list of common words that are commonly used in passwords.
