Social login is a form of single sign-on using existing information from a social networking site such as Facebook, Twitter or Google, to sign into a third party website instead of creating a new login account specifically for that website.
It simplifies logins for end users and provides a method of authentication & authorization for sites & portals.
How it works:
Social-login tool links account from one or more social networking services to a website. By selecting the desired social networking service, the visitor can use his/her existing login to sign on to the website. This helps the end user by negating the need to remember login information for multiple e-commerce sites and other websites.
Why Social Login?
Studies have shown that users do not fill or often fill incorrect data in Registration Forms on websites. Similar studies also indicated that more than 70% of users prefer social login as a means of login & authentication while logging into a web application or an e-commerce website.
Other benefits of Social-Login include:
Quick Sign-up: Websites can use the profile data of user in existing Social Networking Service account instead of having to enter it manually. Thus, saves effort and time of signin-up for the first time.
Validated email: When users use a specified Social Networking service, it is very unlikely for them to enter any false/incorrect email id during registration. This again saves time and effort.
Linkage of account: Users can link existing accounts to their social login account without the need for re-registration.
Targeted Content: With social-login plugin, websites can capture information of users to offer personalized content to the user. This includes information such as name, email, hometown, interests, activities, and friends. This must be done in accordance with the privacy protection regulations and after seeking the consent of the user – obviously!
Multiple Identities: Users can log into websites with multiple social identities allowing them to better control their online identity.
