This article will explain some of the best reCAPTCHA alternatives that can help you combat contact form spam while ensuring a smooth user experience. Ready to explore? Get started!

What is reCAPTCHA?

reCAPTCHA is an updated version of CAPTCHA that was introduced by Google in 2007. Let’s first briefly learn about what CAPTCHA is. It stands for Completely Automated Public Turing test to tell Computers and Humans Apart.

It’s a security system that helps websites verify whether a user is a human or a bot. CAPTCHA typically provides users with challenges like solving distorted texts and images. reCAPTCHA comes with additional security features.

It uses advanced algorithms to analyze human behavior to determine if a user is a bot or a human. reCAPTCHA presents you with puzzles to solve only when it suspects a user. reCAPTCHA v1 and reCAPTCHA v2 would also ask for manual verifications.

reCAPTCHA v3 provides a more friendly user experience by minimizing the need for manual verifications.

Why and when do you need alternatives to Google reCAPTCHA

Why you need alternatives to Google reCAPTCHA

Although CAPTCHA and reCAPTCHA are free to use, you may ask why it is necessary to use their alternatives. Below, we have listed some key points that may inspire you to reconsider finding alternatives to Google ReCaptcha.

a. Privacy concerns

reCAPTCHA largely relies on tracking cookies to analyze user behavior. Collecting user personal data this way may raise conflict under the GDPR law in the EU. If your reCAPCTHA fails to handle GDPR issues, you may have to pay demurrage.

b. Accessibility issues

reCAPTCHA may fail to deal with users having disabilities, particularly those who have visual or hearing impairments. reCAPTCHA may define such users as bots, although they are not. You need a better system to deal with these users.

c. Non-Google users

Not everyone in the world is a Google service user. There are many Apple, Microsoft, and Yahoo users globally. So, relying solely on reCAPTCHA may cause your website to exclude such users, which may cause you to suffer financially in the long run.

d. User experience

Solving quizzes and puzzles whenever logging into websites has become an irritating thing globally to many users. This severely impacts user experience. Integrating a better solution can save them from this boredom.

10 Best Google reCAPTCHA alternatives to prevent form spams

There are many WordPress plugins that you can use on website forms as alternatives to Google reCAPTCHA. We’ll discuss the highly recommended plugins below, including their features and other key points. Keep reading!

WP Armour

Honeypot is a special field on web forms made invisible to legitimate human users using CSS and JavaScript. But spam bots will fill it out because it’s impossible for them to understand that the field is supposed to be hidden.

The reason why spam bots can’t bypass honeypot fields is that they are programmed to fill out all the fields they interact with. When the honeypot field is filled out, it clearly indicates that the submission has come from a bot user.
