How to Prevent WordPress User Registration Process From Spamming

There are multiple approaches to tackling the spam user registration issue in WordPress. But the solution you have to choose will depend on your website’s requirements and the extent of the problem.

So, according to your particular circumstances, you may need to use a single technique or a combination of multiple approaches to stop spam user registrations effectively.

1. Disable the User Registration Option

Before we start, ask yourself a question: Do you need to enable user registration on your WordPress website?

If you operate an eCommerce store or a subscription service, you must allow users to register. However, for personal blogs or business sites, allowing registration may not be necessary.

If you have already registered all the necessary logins, then it is advisable to disable the registration altogether.

To disable user registration on your WordPress website, follow these steps:

  1. Log in to your WordPress dashboard
  2. Go to the “Settings” section and select “General.”
  3. Locate the “Membership” setting and uncheck the box for “Anyone Can Register.”

So there you go! This simple approach guarantees you won’t get spam user registrations anymore. However, this method is only suitable for blogs and business websites that do not allow or need new user registrations.

Nevertheless, if you have no choice but to enable user registration on your website, then let’s explore some other options to minimize the risk of spam registrations.

2. Specify a New User Default Role

If you have decided that you want your WordPress site to remain open for user registration. Then it is absolutely crucial to restrict new members from accessing the admin panel of your WordPress site.

A safe option would be to assign all new users the “Subscriber” role only. With WordPress’ Subscriber role, new users can’t access the dashboard since it has minimal permissions.

To specify the default role for a new user, follow the steps below:

  1. Log in to your WordPress dashboard.
  2. Navigate to the “Settings” section and select “General.”
  3. Finally, select “Subscriber” from the dropdown menu next to “New User Default Role.

3. Use a Dedicated WP Plugin for Registration Approval

One of the challenges with WordPress user registration is that there aren’t many built-in controls to manage the user registration process other than disabling registration or assigning user roles.

But fortunately, there is a solution to this problem! You can use a New User Approve (a dedicated WordPress Plugin for Registration Approval). This tool offers an effective solution to manage and approve new user registrations, ensuring that your site stays safe and secure.
