Frequently Asked Questions
Is my password sent to your server?
No. Password analysis happens entirely in your browser using JavaScript. Your password is never transmitted anywhere.
What makes a strong password?
A strong password is at least 12 characters long and uses a mix of uppercase, lowercase, numbers, and special characters. Avoid dictionary words, names, or predictable patterns like '123456' or 'password'.
