My ASP.NET MVC 4 application uses OpenID2 authentication that went with MVC templates (out of the box) and only uses Google accounts for authentication, no other social features are integrated.
Now I need to migrate OpenID2 because it will be shutdown in April: Migration OpenID2
It seems that I could use one of two options to do this migration:
- OpenID Connect
- Google+ Sign-in
I would like to understand better which differences between the two methods and the advantages/disadvantages of one related to the other.
Until now, I think that the biggest difference is that OpenID Connect is used essencially to authentication and Google+ Sign-in has authentication and social features. Am I right?
