Password Generator

This tool uses the Web Crypto API's cryptographically secure random number generator (crypto.getRandomValues) to select characters. Unlike Math.random(), this method produces truly unpredictable values suitable for security-sensitive purposes, ensuring each generated password is genuinely random.

Security experts recommend a minimum of 12 characters, but 16 or more characters is ideal for important accounts. Each additional character exponentially increases the number of possible combinations, making brute-force attacks impractical. A 16-character password with mixed character types would take billions of years to crack with current computing power.

Yes, using a mix of uppercase letters, lowercase letters, numbers, and symbols significantly increases password strength. A password using all four character types has a much larger character pool (around 95 possible characters per position), making it far more resistant to brute-force and dictionary attacks.

This tool is safe because it runs entirely in your browser with no server communication. The generated passwords are never stored, transmitted, or logged anywhere. You can verify this by using the tool while disconnected from the internet, and it will still work perfectly.

Use a reputable password manager like Bitwarden, 1Password, or KeePass to store your generated passwords securely. Never store passwords in plain text files, browser autofill alone, or sticky notes. A password manager encrypts your vault with a single master password, so you only need to remember one strong passphrase.
