"WooCommerce Social Login - WordPress Plugin!
Enable Social Login for Seamless Checkout and Account
If you have a registration system on your e-commerce
website, then it take too much time of user to checkout
so user get bored of it and thus it will decrease your
sale. But, If you use WooCommerce Social Login, then it
save user’s time so it will increase your sale.
When a customer first visits your site, you can simplify
checkout by allowing them to check out as a guest.
However, this introduces friction for customers that
want to purchase from your store more than once (and
hopefully many of them do!). They’ll have to create yet
another username and password. WooCommerce Social Login
makes this process as easy and secure as possible –
customers can log into your site using their Facebook,
Twitter, Google, Yahoo, LinkedIn, Foursquare, Windows
Live, VKontakte (VK.com), PayPal, Instagram and Amazon
accounts instead of creating a new user account
