Allow a person belonging to a specific Facebook Groups /{user-id}/groups.

How can I allow users from a specific Facebook group to login to my website? We have a library of information that cannot be saved on Facebook. We have created a webpage where this information is listed, but it is only available for registered and approved Facebook members. I have setup the oneall social login with success, but unfortunately anybody with a Facebook account can now access this information. Your assistance would be appreciated as I am not a programmer and the Graph API coding is above me.
Thx
