social login + pop up


Hey there, this sitehttps:// www.spacetennis.com.br/ has a social login, as well as the coolest point is that when going into the website it asks if you intend to utilize your google or facebook info to sign up. Do you recognize which plugin do it. (opens up the popup quickly requesting this info)?

The popup can be taken a drifting home window that shows up when the individual is not visited.
