I have written a step-by-step article on how to add email confirmation when using ASP.NET Identity. You can get the source code here in the project folder AspNetIdentity\AspNetIdentityRefApp. I have also created a service layer that encapsulates ASP.NET Identity, making it easier to incorporate in new MVC 5 applications and mimics the WebSecurity API used by SimpleMembership. You can get that class library from AspNetIdentity\SimpleSecurity.AspNetIdentity There is also reference app for using this library in AspNetIdentity\SimpleSecurity.AspNetIdentity.RefApp. The class library and reference app also show how to implement password reset using a token and basic authentication on Web API’s.
