Common Questions
What makes a password secure and random?
A secure password uses cryptographically random generation (not predictable pseudo-random algorithms), includes a mix of uppercase, lowercase, numbers, and symbols, and is at least 12–16 characters long.
Is this password generator truly random?
Yes. This tool uses the browser's built-in Web Crypto API (crypto.getRandomValues), which produces cryptographically secure random values — the same standard used by security software.
Are my generated passwords stored anywhere?
No. Passwords are generated locally in your browser and are never sent to any server, logged, or stored. Once you close the tab, the password is gone.
How long should a secure password be?
Security experts recommend at least 12 characters for general use, and 16+ characters for sensitive accounts like banking or email. Longer is always stronger.
Can I create a secure password for free?
Yes, this tool is completely free. No account or signup required — just configure your options and click Generate.
Passwords are generated on your device using cryptographic randomness. No password, input, or click is ever sent to a server.
