Secure Password Generator

Why Strong Passwords Matter

Weak passwords are the leading cause of account breaches. Passwords like "password123" or "qwerty" can be cracked in seconds by automated tools. A strong password combines sufficient length with a mix of character types, making brute-force and dictionary attacks impractical.

Security experts recommend passwords of at least 12—16 characters with uppercase letters, lowercase letters, numbers, and symbols. Each additional character exponentially increases the number of possible combinations an attacker must try.

How to Use This Generator

1. Set the length using the slider (6 to 64 characters). We recommend 16 or more for important accounts.
2. Choose character types by checking or unchecking the boxes for uppercase, lowercase, numbers, and symbols.
3. Click "Generate Password" to create a new random password instantly.
4. Click the copy button to save the password to your clipboard, then paste it into your password manager or account settings.

How We Generate Passwords Securely

This tool uses the browser's built-in crypto.getRandomValues() API — the same cryptographically secure random number generator used by modern web applications for encryption keys and security tokens. This is significantly more secure than Math.random(), which produces predictable pseudo-random numbers unsuitable for security purposes.

The entire generation process happens locally in your browser. Passwords are never sent to any server, logged, or stored. When you close the tab, the generated password exists only in your clipboard (if you copied it).

Password Best Practices

• Use a unique password for every account. Reusing passwords means one breach compromises all your accounts.
• Use a password manager. Tools like Bitwarden, 1Password, or KeePass store your passwords securely so you don't need to memorize them.
• Enable two-factor authentication (2FA) wherever possible. Even a strong password is safer with a second verification step.
• Avoid personal information in passwords — no birthdays, names, or common words.
• Change passwords after a breach. If a service you use reports a data leak, generate a new password immediately.
