Google reCAPTCHA v3 – How Does It Affect Your Business?

July 30, 2018

Google has recently launched version 3 of their reCAPTCHA service. Google reCAPTCHA is a security service to protect your website from bots and spam.

You’ve most likely landed on a site that requires you to tick a box saying “I’m not a robot” and type in some text from an image or click boxes that contain cars or street signs. You may very well be using this service on your own site.

These little puzzles are very easy for humans to solve (in theory!) but difficult for computers – making it easy to sift out the bots from the genuine users.

What’s New in Google reCAPTCHA version 3?
One of the new features of the reCAPTCHA v3 update is that it returns a score for each request. Genuine users should get a score close to 1.0, while scores of 0.0 are almost certainly a bot.

With this score, you can code your website to take different actions (such as blocking traffic entirely or requiring 2-factor authentication for low scores). You can also decide on the score threshold at which you want to take action. A score of 0.5 might prompt a security response for some sites, while others that need tighter security might increase this score to 0.9.

The other major change with version 3 of reCAPTCHA is that it’s now invisible to users – no more trying to read ineligible text or click objects in an image.

Scoring is determined purely by natural user actions such as cursor movements and other behaviours so the user doesn’t need to take any action at all unless they’re identified as being suspicious.

As it’s much more user-friendly, Google reCAPTCHA v3 is great for business owners. There’s no more tricky balancing of the need for security against user experience as it’s all managed automatically under the hood of your website.

The scoring system means you also have finer control over how to manage suspicious traffic on your homepage, login, social media, and e-commerce site.

If you want to use the latest version of reCAPTCHA, you’ll need to follow the Google instructions to update the JavaScript on your site.

It’s important to note that reCAPTCHA v3 is still in the BETA phase and being tested before final release. If you choose to use it on your sites now, there may still be some bugs that need to be ironed out.

At Itomic we’re excited at this huge update for reCAPTCHA. It improves the user experience and so can help to increase conversion rates, while giving you better control over the security of your site at the same time.

However, new software updates always come with the possibility of having security holes, especially in the BETA phase, so we’d advise not upgrading to the latest version until it’s officially released.
