Frequently Asked Questions

Common questions about UserCheck

No, an API key is not required to use this plugin. It works out of the box with a limit of 30 requests per hour. However, if you need higher limits, you can obtain a free API key by signing up at https://app.usercheck.com/.
Sign-ups continue to go through and the error is logged for your reference. Your forms keep working even when our service has issues.
To increase the request limit beyond 30 per hour, you can obtain an API key from UserCheck. Once you have the key, go to the UserCheck settings in your WordPress admin panel and enter the key there.
Add a filter in a mu-plugin or your theme's functions.php: add_filter( 'usercheck_block_message', function ( $message, $signal, $email ) { if ( $signal === 'disposable' ) { return 'Please use a permanent email address.'; } return $message; }, 10, 3 ); $signal is one of `blocklisted`, `mx`, `disposable`, `public_domain`, `relay_domain`, `spam`. `$email` is the address being evaluated. Return the (possibly modified) message.
