Registering on websites is hard. So is trying to remember yet another username and password combination. Social login makes it easy for people to register on your site and quickly sign in using the social network or email identities they already have.
With social login, your customers simply select their preferred social identity from Facebook, Google, Twitter or other networks, and choose whether to share some of their information with you. There are no forms to fill out, and makes for one less password to remember. Social login has proven to improve registration conversion rates by at least 50%.
