<p>This WordPress plugin randomizes the user_id for the user created on WordPress setup, removing one potential attack factor from the site.</p>
<h3>How it works</h3>
<p>Once activated, the plugin will immediately replace the ID for the default admin user (with user ID 1). By default, the plugin will use random user IDs between 1 and 4503599627370495 (to ensure compatibility with Javascript code using the user ID).</p>
<p>All newly created users from that moment will be generated with a random user ID in the defined range.</p>
<h3>How to customize the range for new user IDs</h3>
<p>You can customize the range used by the plugin for the random generated user IDs by using the WordPress filters dfx_random_user_id_max_id and dfx_random_user_id_min_id.</p>
<p>For example, if you want to have all your user IDs between 1000 and 9999 you can add the following lines to your theme’s functions.php file:</p>
<pre><code>function set_dfx_max_user_id( $default_max_id ) {
    return 9999;
}
add_filter( 'dfx_random_user_id_max_id', 'set_dfx_max_user_id' );

function set_dfx_min_user_id( $default_max_id ) {
    return 1000;
}
add_filter( 'dfx_random_user_id_min_id', 'set_dfx_min_user_id' );
</code></pre>
<p>Probably, you’ll want to add these lines to your code before activating the plugin, so your new random main admin user ID is inside your desired range.</p>
