FAQ
Is the generated password stored anywhere?
No. Everything is generated in your browser using the Web Crypto API. No data is sent to any server. You can verify this by checking your browser's Network tab.
How strong is a 16-character random password?
A 16-character password using uppercase, lowercase, numbers, and symbols has about 105 bits of entropy. At 10 billion guesses per second, it would take trillions of years to crack by brute force.
What is crypto.getRandomValues()?
It's a Web Crypto API that generates cryptographically secure random numbers. Unlike Math.random(), it uses the operating system's entropy source, making it suitable for security-sensitive operations like password generation.
