Protected Embeds A drop-in replacement for WordPress.com protected embeds
A Human Made project. Maintained by @roborourke.

Installation

1. Install the plugin as normal.
2. Define PROTECTED_EMBEDS_DOMAIN in your wp-config.php as another domain that points to the same WordPress site. For example myembeds.com.

define( 'PROTECTED_EMBEDS_DOMAIN', 'myembeds.com' );

Dealing with early redirects

In WordPress multisite with a domain mapping solution such as Mercator running you may find requests to your embed domain get redirected too early and adding the domain as a site on the network will negate the benefits of a separate domain if you have SSO enabled. You can work around it by adding the following to your sunrise.php file:

// Create a dummy site object pointing the protected embeds domain
// to the primary site
add_filter( 'pre_get_site_by_path', function( $site, $domain, $path ) {
    if ( PROTECTED_EMBEDS_DOMAIN === $domain ) {
        $site          = new stdClass;
        $site->id      = 1;
        $site->blog_id = 1;
        $site->site_id = 1;
        $site->domain  = $domain;
        $site->path    = $path;
        $site->public  = 1;
    }
    return $site;
}, 10, 3 );
