Password Generator

A strong password is one that is long (12+ characters), random (not a dictionary word), and uses a mix of uppercase, lowercase, digits, and special symbols. Password strength is measured by entropy — higher entropy = harder to crack.

A strong password should be at least 12–16 characters long and include uppercase letters, lowercase letters, numbers, and special symbols. Example: 'Kj#9mXp2@vL5'. Avoid dictionary words, names, or patterns.

Key Features

• Uses crypto.getRandomValues() — cryptographically secure randomness.
• Configurable length from 8 to 128 characters.
• Toggle character types: uppercase (A–Z), lowercase (a–z), numbers (0–9), symbols (!@#$%^&*).
• Exclude ambiguous characters (0, O, l, 1) option for easier reading.
• Password never sent to any server — generated entirely client-side.

How to Use the Tool

1. Set your desired password length (default 16 characters).
2. Check the character types you want to include.
3. The password generates instantly. Click 'Regenerate' for a new one.
4. Click 'Copy' to copy to clipboard.

Core Benefits

• Never reuse passwords — generate a unique strong password for every account.
• Eliminates human bias — humans tend to create weak, predictable patterns.
• Much stronger than manually typing a 'random' password.

Common Use Cases

• Creating a new account password for any website or app.
• Generating a strong master password for a password manager.
• Creating temporary passwords for employee accounts.
• Generating API keys or secret tokens (alphanumeric only).

Pro Tips

• Use a password manager (Bitwarden, 1Password, KeePass) — you only need to remember one master password.
• 16 characters with mixed types gives ~10^28 possible combinations — cracking it would take billions of years.
• Never store passwords in plain text documents, emails, or notes apps.
