Block the User Registration Option in WordPress with WPMasterToolKit
By default, WordPress offers an option for visitors to register directly via the administration interface. While this feature may be useful for some community sites, it presents a security risk for the majority of sites, especially blogs, storefronts or online stores that don't require public registration. That's why we've developed the Disallow Register User in WPMasterToolKit, to easily deactivate this option.
Why block user registration?
Disabling public user registration is an important security measure, especially for WordPress sites that don't need this functionality. Here are the main reasons why:
- Reduce brute force attacks : Allowing public registration can open the door to malicious robots trying to exploit this feature to gain access to your site.
- Limit user spam : Sites with open registrations are often the target of spam, creating useless fictitious users.
- Simplify user management By disabling this option, you limit the risk of unauthorized access and retain control over the creation of user accounts.
- Optimizing safety : Blocking registration reduces the overall attack surface of your WordPress site.
How the Disallow Register User module works
The module Disallow Register User deactivates user registration in just a few simple steps. Here are its main features:
Deactivation of the "Anyone can register" option
- The module uses the
pre_option_users_can_register
to force the option to be disabled, preventing users from registering on the site.
Remove option from administration interface
- The module disables the "Anyone can sign up in the general settings page (
options-general.php
). Administrators will no longer see this option enabled, reducing the risk of errors.
Clear user interface
When an administrator accesses the Settings > Generala clear message is displayed next to the deactivated option:
"Deactivated for better securityThis is the only way to ensure that the modification is intentional and motivated by safety reasons.
Lightweight, non-intrusive code
The module uses native WordPress hooks to implement these changes, ensuring compatibility with future WordPress updates.
