About Password Security

Creating strong, unique passwords is essential for protecting your online accounts and personal information. Here's why password security matters:

What Makes a Strong Password?
  • Length: Longer passwords are more secure. Aim for at least 12 characters.
  • Complexity: Include a mix of uppercase and lowercase letters, numbers, and special characters.
  • Unpredictability: Avoid common patterns, words, or personal information.
  • Uniqueness: Use different passwords for different accounts.
Common Password Attacks
  • Brute Force: Attackers try every possible combination until they find the right one.
  • Dictionary Attack: Attempts common words, phrases, and their variations.
  • Credential Stuffing: Using leaked username/password combinations on multiple sites.
  • Phishing: Tricking users into revealing their passwords through fake websites or emails.
Password Management Best Practices
  • Use a reputable password manager to securely store and generate unique passwords
  • Enable two-factor authentication whenever possible
  • Regularly update passwords for critical accounts
  • Check if your accounts have been involved in data breaches using services like "Have I Been Pwned"
  • Consider using passphrases (multiple random words) for passwords that must be memorized

  • Keep passwords stored in a reliable password manager.

Frequently Asked Questions

Can I use this for multiple accounts?

Yes. You can generate multiple strong passwords at once and use a different one for each account.

Are these passwords truly random?

What does "Exclude Similar Characters" mean?
