Social login is a mechanism that allows customers to use the account credentials of a social media site to log in to a third-party service. It makes registering for your product or community easy, thus removing a barrier to acquisition.
The feature also makes logging in again easy, which encourages people to keep coming back.
When someone tries to sign in to your account using their social details, a request is sent to the social network that approves its identity. You just need to integrate your platform with the social network.
Facebook, Twitter, LinkedIn, and Google are some of the most commonly used platforms for social login.
