What is OWIN Concept and is it different from OAuth

Thanks for the reply, but i am not able to understand it clearly.

 

I have searched many articles but there is no such article which can explain about this topic clearly and in a simple way 

OAuth is an open standard for Authorization, which is a token based authorization.

 

Using OAuth, users of a web site or an app can be authenticated by a third party login-password (like Microsoft Live, LinkedIn, Facebook, google) etc. and then a token is returned to your site/app as a representation that authentication has been done.

 

Then, you can use this token to give access to your authenticated users to some resources.

 

While on the other hand OWin is Open Web Interface for .Net. Using OWIN, the tight coupling between a dot net web application  and the server on which it is hosted can be eliminated. It helps eliminate tight coupling between ASP.Net and IIS.

 

I advice to read further by googling.
