Tired of cleaning up fake user registrations from spam bots? KhubaibTech OTP Registration Shield is a lightweight yet powerful security plugin that adds a crucial layer of verification to your WordPress registration form.
Instead of relying on complex CAPTCHAs, this plugin requires users to prove they have access to the email address they are using. It’s a simple, user-friendly process that is incredibly effective at blocking automated spam bots.
How It Works
<ol>
<li>A “Verification Code” field is added to your default WordPress registration form.</li>
<li>The user enters their username and email, then clicks “Send Verification Code.”</li>
<li>A secure one-time password (OTP) is sent to their email.</li>
<li>The user enters the code to complete their registration.</li>
</ol>
This ensures that only users with valid, accessible email addresses can register, drastically reducing spam and improving the quality of your user base.
Key Features:
<ul>
<li>Blocks Spam Bots: Stops automated scripts that create fake user accounts.</li>
<li>Verifies Real Emails: Ensures that every registered user has a valid email address.</li>
<li>Simple for Users: A clean, straightforward verification step.</li>
<li>Lightweight & Secure: No heavy scripts or third-party dependencies. Uses secure WordPress transients and nonces.</li>
<li>Customizable Email: Easily edit the email subject and body from the settings page.</li>
<li>Seamless Integration: Works automatically with the default WordPress registration form.</li>
</ul>

This plugin can sign the webhook events sent by the Gravity Forms WebHooks Add-On to your endpoints by including a signature in each event’s <code>X-Gform-Signature</code> header. This allows you to verify that the events were sent by the Gravity Forms add-on, not by a third party. As of right now, you must verify the signatures by manually using your own solution. However, an example of a Node.js (JavaScript) implementation is linked below.
Before you can verify signatures, you need to retrieve your endpoint’s public key (more information at <a href="#how%20can%20i%20verify%20the%20signature%3F" rel="nofollow ugc">this question</a>).
This plugin uses the same keys for every form and endpoint, meaning that the same keys will be used for every signature generated.
<h3>Verification implementations</h3>
