?Frequently Asked Questions
Can I control the character set?
Yes, you can toggle uppercase, lowercase, numbers, and special symbols to fit your specific requirements (e.g., 'Numbers only' for PINs).
Is it suitable for security?
Yes, we use the browser's crypto.getRandomValues() method, which is suitable for cryptographic purposes, unlike simple Math.random().
