Understanding the Hook: auth_cookie
The auth_cookie hook is located within the wp_validate_auth_cookie function in the wp-includes/pluggable.php file. This function is responsible for validating the authentication cookie and returning the user’s ID if the cookie is valid.

If the auth_cookie hook doesn’t work, it could be due to issues with the authentication cookie itself, such as an expired or invalid cookie. It is also possible that there are conflicts with other plugins or custom code that interfere with the authentication process. To troubleshoot, it is recommended to check for any errors in the authentication process and deactivate any conflicting plugins or custom code.
