I installed the authenticate plugin, but those who sign in with face book skip the click wrap box for terms and conditions. To protect myself, I want to make sure people who sign in or register with face book check a box for terms and conditions to make it binding to them too. Any ideas on how I can implements this on the registration page and also on the sign in with facebook page?

You would need plugin (or modification), that once user register using social network, once logged in, popup to accept terms and conditions is shown with no option to close it - only consent and submit.

Would you please show me which plugin can do that? Or what code I can add to make that modification? I will really appreciate it.

@Cephas
I do not think there is currently such plugin, was just drawing idea that would work.
