Asp.net development is an interesting platform and major developers today, are learning and grasping skills to make best development practices. This article is about asp.net developers techniques to authenticate social media in mvc. You will learn every step involved in the process of authentication of FB/Google+ in mvc development.
In this section we covered following points,
One of the core functions of any modern web site is the ability to leverage Social Authentication (also known as Social Login).
Normally in any web site we develop there are two common features is there login and registration. In registration we ask basic information to fill from user. And at the back we store user filled information in database and give user unique identification through we identify user when it’s login into our web site. Now a day’s everything is online and most of the work is done through web. So as user point of you, he/she might be go through normal procedure to fill form and register and after registration login and access the web site.
So, Social login is a form of single sign-on using existing login information from an identity provider such as Facebook, Twitter, Google or Microsoft to sign into a third party website and using third party response creating a new login account specifically for your web site.
Is Login with social media is secure?
Social login is actually powered by OAuth. OAuth is an open standard for authorization. OAuth provides client applications 'secure delegated Access’ to server resources on behalf of a resource owner. It specifies a process for resource owners to authorize third-party access to their server resources without sharing their credentials. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner, or end-user. The client then uses the access token to access the protected resources hosted by the resource server. OAuth is commonly used as a way for web surfers to log into third party web sites using their Facebook, Twitter, Google or Microsoft accounts, without worrying about their access credentials being compromised.

How to implement login with Facebook and Google+

Rest of the other process is same as Facebook so, convert response in JSON Object and invoke particular controller action method to further process the login request.
The author has used simple coding and techniques to make you learn the process about authentication of FB/ Google+ in mvc development. This article is purposely intended for asp.net developers and development community, indeed.
