About Password Generator
Weak passwords are the number one cause of account breaches. Our free Password Generator creates cryptographically random, strong passwords using your choice of character sets — uppercase, lowercase, numbers, and symbols — at any length you specify. All generation happens in your browser using the Web Crypto API — no passwords are ever logged, transmitted, or stored anywhere.
Security experts recommend passwords of at least 16 characters with a mix of uppercase letters, lowercase letters, numbers, and symbols. Reusing passwords across sites is the primary risk factor in credential stuffing attacks. Our generator creates unique, unpredictable passwords for every account, making it the first step toward a strong security posture.
The generator uses window.crypto.getRandomValues() — the browser's cryptographically secure pseudorandom number generator (CSPRNG) — which is the same source of randomness used by banking apps and encryption software. This is significantly more secure than Math.random()-based generators used by lesser tools.
The tool also provides a password strength meter so you can see the estimated entropy (in bits) of each generated password, and a memorable passphrase generator (words separated by dashes or spaces) for situations where you need to type the password manually.
How to Use the Password Generator
Set password length
Use the slider to choose length — 16 characters is minimum for strong passwords; 24–32 is recommended for critical accounts.
Choose character sets
Toggle uppercase letters, lowercase letters, numbers, and symbols independently.
Generate
A cryptographically random password appears instantly. Click the refresh icon to generate a new one.
Copy securely
Click the copy icon to copy to clipboard. The password is never shown again after you navigate away — save it in a password manager immediately.

Frequently Asked Questions
Very secure. We use the Web Crypto API's cryptographically secure random number generator. A 20-character password with all character sets enabled has approximately 130 bits of entropy — far beyond what any brute-force attack can crack.
Using a dedicated password manager (Bitwarden, 1Password, KeePass) is safer than browser autofill, which can be accessed by malicious browser extensions.
Include all four (uppercase, lowercase, numbers, symbols) for maximum entropy. If a site doesn't allow symbols, use uppercase + lowercase + numbers with a length of 20+.
