What does "Request Access Token On Connect" Mean?

Under Android in the project settings…there’s a section for google play services…I cannot seem to find documentation on what “Request Access Token On Connect” means. Any Idea?

could you send a screenshot?

It will prompt the user to allow GET_ACCOUNTS as a permission, this will also be added to your manifest XML. It’s needed for achievements and possibly other Google Play related assets. I do, however, believe that this permission is used solely in older versions of Android. I might be wrong on that…

Thanks!
