FAQ

Are the generated passwords secure?

Yes. This tool uses the cryptographically secure random number generator (crypto.getRandomValues). Unlike Math.random(), it provides unpredictable randomness.

How is password strength determined?

Strength is based on length, character type diversity, and entropy (bits of information). Generally, passwords of 12+ characters with multiple character types are rated as "strong".

Is my data sent to a server?

No. All password generation happens locally in your browser. Generated passwords are never transmitted externally.
