What is ReCAPTCHA?
reCAPTCHA is a free service created by Google that helps protect websites from spam and abuse. It uses advanced risk analysis techniques to distinguish humans from bots that try to engage in abusive activities on websites.
The core functionality of reCAPTCHA is the use of CAPTCHAs - challenges that are easy for humans to solve but difficult for bots. However, reCAPTCHA also offers captcha alternatives for use cases where CAPTCHAs would create accessibility issues or impact user experience.
There are different versions of reCAPTCHA available:
- reCAPTCHA v2 - Offers flexible CAPTCHAs and captcha alternatives like one-click verification for low risk traffic.
- reCAPTCHA v3 - Runs adaptive risk analysis in the background without user interaction. Suitable for high traffic sites.
- Invisible reCAPTCHA - Uses advanced risk analysis to let most humans through without interactions while stopping bots.
Overall, reCAPTCHA helps prevent spam and abuse on websites in a user-friendly way while also providing options to website owners. Over 580 million active sites use reCAPTCHA today.
