A strong password is your first line of defense against unauthorized access to your accounts. Understanding what makes a password strong can help you create better passwords and protect your digital identity.
Key Elements of Password Strength
Length
Longer passwords are generally more secure. Aim for at least 12 characters, but 16 or more is better.
Complexity
Use a mix of uppercase and lowercase letters, numbers, and special characters to increase complexity.
Unpredictability
Avoid common words, phrases, or patterns like "password123" or sequential numbers like "12345".
Uniqueness
Use different passwords for different accounts. If one is compromised, others remain secure.
Password Security Tips
- Consider using a passphrase (a sequence of random words) which can be both secure and memorable.
- Use a password manager to generate and store strong, unique passwords for all your accounts.
- Enable two-factor authentication (2FA) whenever possible for an extra layer of security.
- Change your passwords periodically, especially for critical accounts.
- Never share your passwords with others or use the same password across multiple sites.
