Type

Access extension

Additional requirements

reCAPTCHA API key (creation page)

Installation notes

Download the reCAPTCHA extension and extract it into the directory /extensions/recaptcha/.

Download a newer version of the ConfirmEdit extension and extract only the files ConfirmEdit.i18n.php, ConfirmEdit.php and ConfirmEdit_body.php into that same directory, replacing the already existing files.

In the /LocalSettings.php, remove the following line to disable the original ConfirmEdit extension:

require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" );

Insert the following lines to activate the reCAPTCHA extension, and fill in the API key details as required:

require_once( "$IP/extensions/recaptcha/ReCaptcha.php" );
$recaptcha_public_key  = ''; // reCAPTCHA public key
$recaptcha_private_key = ''; // reCAPTCHA private key

Finally, update the previously (with the ConfirmEdit extension) made settings to reflect these changes:

$wgGroupPermissions['*'            ]['skipcaptcha'] = false;
$wgGroupPermissions['user'         ]['skipcaptcha'] = false;
$wgGroupPermissions['autoconfirmed']['skipcaptcha'] = true;
$wgGroupPermissions['bot'          ]['skipcaptcha'] = true;
$wgGroupPermissions['sysop'        ]['skipcaptcha'] = true;

$wgCaptchaTriggers['edit']          = false;
$wgCaptchaTriggers['create']        = false;
$wgCaptchaTriggers['addurl']        = true; 
$wgCaptchaTriggers['createaccount'] = true;
$wgCaptchaTriggers['badlogin']      = true;

Reason for the request

While the current CAPTCHA offers basic protection, it can be too easily parsed by bots and with the current events it is no longer appropriate. reCAPTCHA offers a standardized way to present the CAPTCHA with an acceptable level of accessibility.
