Internationalization Single Sign-On
One login to rule them all
This module is primarily intended for multilingual sites that detect the user language via the URL and which utilize different top-level domains (TLDs).
You may have both example.com and example.es, for example.
Administration of such sites can often be frustrating, since cookie policies do not allow example.es to read the session cookies set upon login to example.com. Users and administrators must therefore log into each site separately, even though the installation of Drupal is the same.
When enabled, this module will, upon successful login, log the user into the site in each language via special URLs. This is done using single-use, time-limited authentication tokens that are only intended to last for a few seconds.
You don't need to configure anything. Just turn off the module if you don't want the functionality anymore.
It is recommended to serve i18n_sso/* paths over HTTPS. That will provide extra security.
