Generate Multiple Passwords

How to Use the Password Generator

  1. Adjust the length using the slider. Longer passwords are more secure (16+ recommended).
  2. Select character types — uppercase, lowercase, numbers, and symbols. Using all types makes passwords strongest.
  3. Click "Regenerate" to create a new password, or "Copy Password" to copy it to your clipboard.
  4. Generate multiple passwords at once using the button at the bottom.

All passwords are generated entirely in your browser using the Web Crypto API. No passwords are stored, transmitted, or logged anywhere. This tool is completely client-side and private.

Why Strong Passwords Matter

Weak passwords are the leading cause of data breaches. A simple 6-character password can be cracked in seconds using modern hardware. An 8-character password with mixed characters takes about 8 hours. A 12-character password with uppercase, lowercase, numbers, and symbols would take centuries to crack with brute force. Every additional character multiplies the possible combinations exponentially.

Password Best Practices

Use at least 12 characters — longer is always better. Mix character types: uppercase, lowercase, numbers, and symbols. Never reuse passwords across different accounts. Use a password manager (like Bitwarden, 1Password, or KeePass) to store unique passwords for every account. Enable two-factor authentication (2FA) wherever possible for an additional security layer.

How This Generator Works

This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random number generation. Unlike Math.random(), which uses a pseudo-random algorithm, crypto.getRandomValues draws from your operating system's entropy source, making the generated passwords truly unpredictable. All generation happens locally in your browser — no passwords are ever sent to or stored on any server.
