Password Security Tips

Length Matters

Longer passwords are more secure. Each additional character exponentially increases the time required to crack a password. Aim for at least 12 characters for important accounts.

Unique Passwords

Use different passwords for different accounts. This prevents a breach in one account from compromising all your other accounts. Never reuse passwords for critical services.

Password Managers

Consider using a reputable password manager to generate and store complex, unique passwords securely. Password managers help you maintain strong passwords without having to remember them all.

Two-Factor Authentication

Enable two-factor authentication (2FA) whenever possible for an additional layer of security beyond your password. This provides protection even if your password is compromised.

Frequently Asked Questions

A strong password typically has the following characteristics:

  • At least 12 characters in length
  • A mix of uppercase and lowercase letters
  • Includes numbers and special characters
  • Avoids common words, phrases, or predictable patterns
  • Is not reused across different accounts

Our password generator creates strong passwords by incorporating these principles while allowing you to customize options based on your needs.

Excluding similar characters (like i, l, 1, L, o, 0, O) makes passwords easier to read and type correctly, reducing frustration when manually entering passwords. This is especially helpful for passwords you might need to type frequently or share verbally.

While excluding these characters slightly reduces the potential character pool, the impact on security is minimal when using sufficiently long passwords with other complexity factors.

Our password strength and crack time estimations are based on several factors:

  • Password length
  • Character set diversity (lowercase, uppercase, numbers, symbols)
  • Total possible combinations based on these factors
  • Estimated computing power of modern cracking attempts

These calculations provide a reasonable approximation of password security but should be considered estimates. Always err on the side of caution with sensitive accounts by using maximum complexity and length.

Yes, our password generator is secure to use because:

  • All password generation happens locally in your browser
  • No passwords are stored on our servers
  • No passwords are transmitted over the internet
  • The tool uses cryptographically secure random number generation methods

For maximum security, we recommend generating passwords while not connected to public Wi-Fi and clearing your browser history after using the tool if you're on a shared computer.
