Let’s now delve into the 15 rules outlined in the NIST Password Guidelines 2024.

  1. Use passwords that are at least 12 characters long.
    Longer passwords are inherently more secure than shorter ones. The NIST Password Guidelines recommend using passwords that are at least 12 characters long.
    Longer passwords provide more entropy, making them harder to crack through brute-force attacks. It is crucial to choose a combination of upper-case and lower-case letters, numbers, and special characters to enhance the complexity of your password.
  2. Avoid commonly used passwords
    Avoid using commonly used passwords such as “password,” “123456,” or “qwerty.” These passwords are incredibly weak and are often the first choices for hackers attempting to gain unauthorized access. Instead, opt for unique passwords that are not easily guessable. Consider using a combination of random words or phrases to create a strong and memorable password.
  3. Implement two-factor authentication
    Two-factor authentication (2FA) provides an additional layer of security by requiring users to provide two forms of identification before accessing an account. This typically involves a password and a unique verification code sent to a trusted device. Implementing 2FA significantly reduces the risk of unauthorized access, even if your password is compromised.
  4. Use a password manager
    With the increasing number of online accounts we have today, remembering unique and complex passwords for each one can be challenging. Password managers are invaluable tools that securely store all your passwords in one place.
    They can generate strong passwords and even automatically fill them in for you. Using a password manager simplifies the process of managing multiple passwords while ensuring their security.
  5. Regularly update passwords
    It’s important to periodically update your passwords to minimize the risk of unauthorized access. The NIST Password Guidelines recommend changing your passwords every six months, or sooner if you suspect any compromise. Regularly updating your passwords helps mitigate the potential damage caused by a password breach and ensures the continued security of your accounts.
