As of reCaptcha v1.2.1 an API was added which plugins must now use to enable support. Plugin Integration for reCAPTCHA is now controlled in the Plugins own Configuration and not the reCAPTCHA configuration.
Geeklog's reCAPTCHA plugin supports both reCAPTCHA V2 (with checkbox and invisible) and reCAPTCHA V3. Each of them will require you to setup on the Google reCAPTCHA website (https://www.google.com/recaptcha/admin/create). You will need to create an account and add your site and create a site key and a secret key to be able to use the free service.
reCAPTCHA V2 requires the user to click a checkbox indicating the user is not a robot. This will either pass the user immediately (with No CAPTCHA) or challenge them to validate whether or not they are human.
Unlike reCAPTCHA with checkbox, these do 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. By default only the most suspicious traffic will be prompted to solve a captcha. To alter this behavior edit your site security preference under advanced settings on the Google reCAPTCHA website.

| enable_contact | reCAPTCHA V3 | If you set this to reCAPTCHA V2, reCAPTCHA with checkbox (version 2) will be enabled for contact form. If set to reCAPTCHA V2 invisible, the V2 invisible version will be used. |
| enable_emailstory | reCAPTCHA V3 | If you set this to reCAPTCHA V2, reCAPTCHA with checkbox (version 2) will be enabled for "Email Story" form. If set to reCAPTCHA V2 invisible, the V2 invisible version will be used. |
| enable_registration | reCAPTCHA V3 | If you set this to reCAPTCHA V2, reCAPTCHA with checkbox (version 2) will be enabled for registration. If set to reCAPTCHA V2 invisible, the V2 invisible version will be used. |
| enable_story | reCAPTCHA V3 | If you set this to reCAPTCHA V2, reCAPTCHA with checkbox (version 2) will be enabled for "Story Submission" form. If set to reCAPTCHA V2 invisible, the V2 invisible version will be used. |
| enable_getpassword | reCAPTCHA V3 | If you set this to reCAPTCHA V2, reCAPTCHA with checkbox (version 2) will be enabled for "Get Password" form. If set to reCAPTCHA V2 invisible, the V2 invisible version will be used. |

If set to reCAPTCHA V2 invisible, the V2 invisible version will be used. Important: If any type of CAPTCHA is enabled for the user login you must disable Read Access for Anonymous users for the User Functions block. The Block Name is "user_block" and you can find the permission under Access Rights on the Block Editor form. The reason for this is because this block will display a mini login form that does not support reCAPTCHA and therefore will always fail to login the user from it. Do not disable this block completely as the User Functions block is needed once users are logged in. You should then make sure the login menu element is enabled in the Geeklog Configuration so users can find out how to access the full page login form. |
