This extension lets your visitors register and log in to your directory site using their social profiles (Facebook and Google) instead of forcing them to spend valuable time filling out the default registration form. Besides that, they dont need to wait for validation emails or keep track of their username and password anymore.
Not everyone likes filling out registration forms and it often drives users away from the site. Keeping that into account, offering single-click Google and Facebook login options will allow users to have a compelling user experience and surely, will attract more visitors.
