We develop and integrate facebook plugin for our client’s website. Social login is a form of single sign-on using existing login information from a social networking service such as Facebook, Twitter or Google+ to sign into your website by creating a new login account specifically for your website. While a user sign in your website with his social account details then automatically a registration process happening in background and the user’s account profile details are fetched from the social networking website and stored in your website database.
Social login can be implemented strictly as an authentication system using standards such as OpenID or SAML. For consumer websites that offer social functionality to users, social login is often implemented using the OAuth standard. OAuth is a secure authorization protocol which is commonly used in conjunction with authentication to grant 3rd party applications a “session token” allowing them to make API calls to providers on the user’s behalf. Sites using social login in this manner typically offer social features such as commenting, sharing, reactions and gamification.
While social login can be extended to corporate websites, the majority of social networks and consumer-based identity providers allow self-asserted identities. For this reason, social login is generally not used for strict, highly secure applications such those in banking or health.
Advantages of social login
Studies have shown that website registration forms are inefficient as many people provide false data, forget their login information for the site or simply decline to register in the first place. A study conducted during in 2011 by Janrain and Blue Research found that 77 percent of consumers favored social login as a means of authentication over more traditional online registration methods.Additional benefits:
- Targeted Content – Websites can obtain a profile and social graph data in order to target personalized content to the user. This includes information such as name, email, hometown, interests, activities and friends.
- Multiple Identities – Users can log in to websites with multiple social identities allowing them to better control their online identity.
- Registration Data – Many websites use the profile data returned from social login instead of having users manually enter their PII (Personally Identifiable Information) into web forms. This can potentially speed up the registration or sign-up process.
- Pre-Validated Email – Identity providers who support email such as Google and Yahoo! can return the user’s email address to the 3rd party website preventing the user from supplying a fabricated email address during the registration process.
- Account linking – Because social login can be used for authentication, many websites allow legacy users to link pre-existing site account with their social login account without forcing re-registration.
