Sick of typing those annoying, and barely readable, letters and numbers to prove to a website that you’re not a robot or a spammer?

You may be in luck.

Google announced Wednesday that the company is trying to get rid of those annoying tasks called CAPTCHAs, which is short for Completely Automated Public Turing test to tell Computers and Humans Apart.

Instead of requiring that users fill in the letters and numbers shown in a distorted image, sites that use Google’s reCAPTCHA service will be able to use just one click, answering a simple question: Are you a robot?

“reCAPTCHA protects the websites you love from spam and abuse,” wrote Vinay Shet, product manager for Google’s reCAPTCHA service, in a blog post. “For years, we’ve prompted users to confirm they aren’t robots by asking them to read distorted text and type it into a box… But, we figured it would be easier to just directly ask our users whether or not they are robots. So, we did! ”

Google on Wednesday began rolling out a new API that rethinks the reCAPTCHA experience.

CAPTCHA “can be hard to read and frustrating for people, particularly on mobile devices,” said Zeus Kerravala, an analyst with ZK Research. “People often have to put in the text several times. On the surface, this seems a good way to improve the user experience. It still requires human intervention, just something simpler.”

CAPTCHAs were created to foil computer programs that hackers or spammers use to troll for access to websites or to collect email addresses.
