The Google Recaptcha is now on ODC!
reCAPTCHA v3: Allows you to verify if an interaction is legitimate without any user interaction. You can see a brief explanation of this tool in this Google video. For more extensive documentation read Google's reCAPTCHA v3 official page.
reCAPTCHA v2 Checkbox: The "I'm not a robot" Checkbox requires the user to click a checkbox indicating the user is not a robot. You can see a brief explanation of this tool in this Google video. For more extensive documentation read Google's reCAPTCHA v2 CheckBox official page.
reCAPTCHA v2 Invisible: The invisible reCAPTCHA does not require the user to click on a checkbox, instead it is invoked directly when the user clicks on an existing button on your site or can be invoked via a JavaScript API call. By default, only the most suspicious traffic will be prompted to solve a captcha. For more extensive documentation read Google's reCAPTCHA v2 Invisible official page.
