function updateRecaptchaSize() {
// Select all elements with the 'data-size' attribute
const recaptchas = document.querySelectorAll('[data-size]');
if (recaptchas.length > 0) {
const isMobile = window.matchMedia("(max-width: 767px)").matches; // Adjust breakpoint as needed
// Update each reCAPTCHA's data-size attribute
recaptchas.forEach(recaptcha => {
recaptcha.setAttribute("data-size", isMobile ? "compact" : "normal");
});
}
}
// Run on load
updateRecaptchaSize();
// Run on resize
window.addEventListener("resize", updateRecaptchaSize);
});

Google CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security tool designed to prevent bots and automated scripts from accessing websites. By requiring users to complete simple tasks, such as selecting images or checking a box, CAPTCHA helps differentiate between humans and bots.
Bots can fill out forms, submit fake comments, and engage in fraudulent activities. CAPTCHA stops automated scripts from misusing website functionalities.
Brute force attacks, credential stuffing, and data scraping are common cyber threats. CAPTCHA helps mitigate these risks by blocking automated access attempts.
By preventing unauthorized access, CAPTCHA plays a crucial role in securing user accounts and sensitive information.
