Password Security Tips

Use Unique Passwords

Never reuse passwords across different accounts. A breach on one site could compromise all your accounts.

Enable Two-Factor Authentication

Add an extra layer of security by requiring a second verification step beyond just your password.

Change Passwords Regularly

Update important passwords every 3-6 months to minimize the risk of unauthorized access.

Use a Password Manager

Securely store and manage all your passwords in one place with encryption.

Common Password Mistakes

  • Using personal information (names, birthdays, addresses)
  • Using dictionary words or common phrases
  • Repeating characters (e.g., "aaaaa" or "12345")
  • Using short passwords (less than 12 characters)
  • Not mixing character types (only letters or only numbers)
