Frequently Asked Questions
How secure are these passwords?
Very secure. We use the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. The entropy indicator shows the actual strength in bits.
Are passwords stored or sent anywhere?
No. All passwords are generated entirely in your browser using the Web Crypto API. No data is sent to any server.
What makes a strong password?
A strong password uses a mix of uppercase, lowercase, numbers, and symbols. It should be at least 16 characters long. Our strength indicator helps you assess password quality.
