Tips and Common Mistakes to Avoid

  • Always use at least 12 characters. Short passwords are significantly easier to crack even with mixed character types.
  • Never reuse the same password across multiple accounts. Generate a unique password for each service you use.
  • Include all four character types (uppercase, lowercase, numbers, specials) for maximum strength and entropy.
  • Avoid passwords based on personal information like birthdays, names, or common dictionary words.
  • Consider using a password manager to securely store and manage your generated passwords across devices.
  • Change passwords regularly, especially for critical accounts like email, banking, and social media.

Frequently Asked Questions

Is this password generator safe to use?
Yes, this password generator runs entirely in your browser. No passwords are sent to any server or stored anywhere. Your generated passwords remain completely private on your device. The tool uses the Web Crypto API for secure randomness when available.
What is the recommended password length?
Security experts recommend using passwords that are at least 12 to 16 characters long. Longer passwords with a mix of character types are significantly harder to crack. Our tool supports up to 128 characters for maximum security.
Can I generate passwords without special characters?

What makes a password strong?
A strong password is typically long (12 or more characters) and uses a mix of uppercase letters, lowercase letters, numbers, and special symbols. Avoid using dictionary words, personal information, or common patterns like "123456" or "password".
