The Google test for reCaptch. Tell if your a robot or not
reCAPTCHA protects your website from fraud and abuse without creating friction.
reCAPTCHA uses an advanced risk analysis engine and adaptive challenges to keep malicious software from engaging in abusive activities on your website. Meanwhile, legitimate users will be able to login, make purchases, view pages, or create accounts and fake users will be blocked.
reCAPTCHA Enterprise provides a frictionless user experience where fraud protection is easily extended across websites rather than being limited to select pages. It can be integrated into your mobile application using an API-based service.
reCAPTCHA v2 verifies if an interaction is legitimate with the “I am not a robot” checkbox and invisible reCAPTCHA badge challenges.
reCAPTCHA v3 verifies requests with a score and gives you the ability to take action in the context of your site.
