Facebook login inside contact form 7?

What I ultimately want to do is this –
1. Give visitors the option of registering for new blog post notifications with their Facebook account, or via fill-in form with name and email.

I currently capture name and email with contact form 7 – but no Facebook registration.

2. Have the registration info – name, email, plus location from Facebook – emailed to me (contact form 7 already does this for me).

** Can a Facebook registration and info-gathering popup be added to my form contact form 7?

** If so, can I use another plugin to add the shortcode, or generate it?
