Frequently Asked Questions

In this specific script, clicking Cancel will act as a wrong guess and simply re-prompt the user or alert them that access is denied.

No. The PIN is visible in the JavaScript source code. This is suitable for very basic protection (e.g., a child's game page) but not for sensitive data.

Yes. You can add a counter variable (e.g., 'var tries = 0') and break the loop if it exceeds 3 attempts.
