To know more about the\nfeatures of reCAPTCHA and reCAPTCHA Enterprise, see [Comparison of features between reCAPTCHA versions](https://cloud.google.com/recaptcha/docs/compare-tiers).\n\nThis document provides an overview of Google reCAPTCHA v3 and v2. For\ninformation about reCAPTCHA Enterprise, see the\n[reCAPTCHA Enterprise documentation](https://cloud.google.com/recaptcha/docs/overview).\n\nTo get started with reCAPTCHA Enterprise, you can use our\n[Site Registration Tool](https://www.google.com/recaptcha/admin/create). This\ntool will help you create a new reCAPTCHA Site Key, and if needed also create a\nnew Google Cloud account.\n\n[Get Started](https://www.google.com/recaptcha/admin/create)\n\nAudience\n--------\n\nThis documentation is designed for people familiar with HTML forms, server-side processing or mobile\napplication development. To install reCAPTCHA, you might need to edit some code.\n\nWe hope you find this documentation easy to follow. You can ask a question about reCAPTCHA on\n[Stack Overflow](https://stackoverflow.com/questions/tagged/recaptcha), using the tag `recaptcha`.\n\nOverview\n--------\n\nTo start using reCAPTCHA, you need to [sign up for an API key\npair](http://www.google.com/recaptcha/admin) for your site. The key pair consists of a site key and\nsecret key. The site key is used to invoke reCAPTCHA service on your site or mobile application. The\nsecret key authorizes communication between your application backend and the reCAPTCHA server to\n[verify the user's response](/recaptcha/docs/verify). The secret key needs to be kept safe for\nsecurity purposes.\n\nFirst, choose the [type of reCAPTCHA](/recaptcha/docs/versions) and then fill in authorized domains\nor [package\nnames.](https://developer.android.com/guide/topics/manifest/manifest-element.html#package) After you\nhave accepted the terms of service, click **Register** to get new API key pair.\n\nNow, perform the following steps to add reCAPTCHA to your site or mobile application:\n\n1. Choose the client-side integration:\n - [reCAPTCHA v3](/recaptcha/docs/v3)\n - reCAPTCHA v2\n - [Checkbox](/recaptcha/docs/display)\n - [Invisible](/recaptcha/docs/invisible)\n - [Android](https://developer.android.com/training/safetynet/recaptcha.html)\n2.
