RIACO Content Protector allows you to protect any part of your WordPress content using a shortcode. 
Unlike the built-in post password protection, this plugin protects only what you wrap, not the whole post.
Perfect for:
<ul>
<li>Protecting premium blocks of content </li>
<li>Protecting guides, downloads, links, or sensitive sections </li>
<li>Paywall-style snippets</li>
</ul>
<h3>Features</h3>
<ul>
<li>Protect only specific content inside posts/pages </li>
<li>Uses a minimal shortcode: 
 [riaco_content_protector] Hidden text here [/riaco_content_protector]</li>
<li>Global password stored in plain text, like WordPress page passwords.</li>
<li>AJAX-based form — no page reload </li>
<li>Unlocks all protected sections on the site after correct password </li>
<li>Optional cookie persistence (remember unlocked content for a configurable number of days) </li>
<li>Secure implementation using nonces, hashed tokens, and transients </li>
</ul>
Important:
<ul>
<li>The global password is stored in plain text, just like WordPress page passwords. It can be read by user with ‘manage_options’ ability.</li>
<li>If the global password or “Remember Unlocked” duration is changed in settings, all existing unlock cookies are invalidated. Users will need to re-enter the new password to access protected content.</li>
</ul>
<h3>How It Works</h3>
Wrap content you want to protect:
<pre><code>[riaco_content_protector]
This text will be hidden until the visitor enters the password.
[/riaco_content_protector]
</code></pre>
Set the global password under:
Settings > Content Protector
Visitors will see a modern, styled form. 
After entering the correct password:
<ul>
<li>The content unlocks immediately </li>
<li>All other protected areas unlock automatically </li>
<li>An optional cookie can keep everything unlocked for a chosen number of days </li>
</ul>
<h3>Security</h3>
<ul>
<li>Nonces on every request </li>
<li>Secure HMAC token for cookie authentication </li>
<li>Sanitized shortcode attributes </li>
<li>Escaped output </li>
<li>No sensitive data stored in cookies </li>
<li>Global password stored in plain text, like WordPress page passwords. </li>
</ul>
<h3>Cookie</h3>
We use this cookie to understand if user unlocked the content: <code>riaco_cp_unlocked_global</code>.
<h3>Style</h3>
You can style the content protector box.
It has this class: <code>.riaco-cp--container</code>, so you can add in your <code>style.css</code>:
<pre><code>.riaco-cp--container {
 background: #f8f9fa;
 padding: 20px;
 border: 1px solid #ddd;
 border-radius: 6px;
}
</code></pre>
You can replace button classes using:
<pre><code>add_filter( 'riaco_cp_button_classes', function( $classes ) {
 return 'button my-custom-button-class';
});
</code></pre>
Or you can remove button classes:
<pre><code>add_filter( 'riaco_cp_button_classes', function( $classes ) {
 // Remove wp-element-button
 return str_replace( 'wp-element-button', '', $classes );
});
</code></pre>
