Generate truly random passwords using Web Crypto API. Up to 128 characters with custom character sets.
Yes — passwords use the Web Crypto API's getRandomValues(), which is cryptographically secure and cannot be predicted.
No. Everything runs in your browser. No data ever touches a server.
At least 16 characters for important accounts. 20+ with all character types is very strong.
Set the password length using the slider, choose which character types to include (uppercase, lowercase, numbers, symbols), and click Generate. Click Copy to copy it to clipboard.
Use at least 16 characters with all four character types for maximum security. Never reuse passwords across sites. Store generated passwords in a password manager like Bitwarden or 1Password.
Generate cryptographically random, strong passwords of any length. Choose from uppercase, lowercase, numbers, and special characters. Generate multiple passwords at once. Check password strength instantly. All generation happens locally — passwords never touch any server.
Password generation uses the browser's window.crypto.getRandomValues() — a cryptographically secure randomness source. Generated passwords are never logged or transmitted.
Choose password length — 16+ characters is recommended for security.
Toggle uppercase, lowercase, numbers, and special characters.
Click Generate — or regenerate until you get one you like.
Click the password to copy to clipboard.
16 characters minimum for regular accounts; 24+ for critical accounts like banking or email.
No — generation uses browser crypto APIs. Passwords are never stored or transmitted.
Use the passphrase mode to generate word-based passwords like "correct-horse-battery-staple" that are easier to remember.
A password with uppercase, lowercase, numbers, and symbols has vastly more possible combinations — harder to brute-force.
Yes — store generated passwords in a password manager like Bitwarden, 1Password, or KeePass.
