\nThis was actually intented for a Multi-Network-Multi-Site Word Press installation. But I can work with single separated Word Press installations. You only require that the users have the same username and password among sites.<\/p>\n

Single Sign-On between different WP installations<\/h4>\n

Find this part in your root or parent wp-config.php (\/).
\n[php]
\n\/**#@+
\n * Authentication Unique Keys and Salts.
\n *
\n * Change these to different unique phrases!
\n * You can generate these using the {@link https:\/\/api.wordpress.org\/secret-key\/1.1\/salt\/ WordPress.org secret-key service}
\n * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.

\nAdd this just below it:
\n[php]
\ndefine(‘COOKIE_DOMAIN’, false);
\ndefine(‘ADMIN_COOKIE_PATH’, ‘\/’);
\ndefine(‘COOKIEPATH’, false);
\ndefine(‘SITECOOKIEPATH’, false);
\ndefine(‘COOKIEHASH’, md5(‘http:\/\/YOUR_ROOT_SITE’));
\n[\/php]
\nNow copy the entire block from this root file wp-config.php (\/) and replace it in the new installation wp-config.php (\/blogs\/) file.

\nThe important part here is that the characters ‘SOME CRAZY CHARACTERS YOUR INSTALLATION GENERATED’ are the same between installations.<\/p>\n

I haven’t tryied this on a separate domain installation. But this works great on subdirectories installation.<\/p>\n

Hope this works for you as much as it\u2019s been working for me so far.<\/p>\n","protected":false},"excerpt":{"rendered":"
