OpenRA

says Authentication key is not connected to open ra account. where do i put this?

Hi, you need to put the key here: ucp.php?i=232

However, that is not needed to create a private game. Simply go to the Multiplayer Menu and click "Create". There you can set a password so that only your friends can join.

It sounds like your authentication key isn’t properly linked to your OpenRA account. Double-check your account settings on the OpenRA website, where you should find a section for entering your key to activate account-linked features.
