PASSWORD SECURITY TIPS

Creating strong, unique passwords is essential for protecting your online accounts. Here are some tips for creating better passwords:

  • Use at least 12 characters - longer passwords are generally more secure
  • Include a mix of uppercase letters, lowercase letters, numbers, and special characters
  • Avoid using easily guessable information like your name, birthday, or common words
  • Don't reuse passwords across different accounts
  • Consider using a passphrase - a sequence of random words that's easy for you to remember but hard for others to guess
  • Use a password manager to generate and store complex passwords securely
  • Enable two-factor authentication (2FA) whenever possible for an extra layer of security

ABOUT PASSWORD ENTROPY

Password entropy is a measurement of how unpredictable a password is. It's calculated based on the length of the password and the size of the character set used. Higher entropy means a password is more resistant to brute force attacks.

A good password should have at least 60 bits of entropy to be considered reasonably secure against modern attacks.
