I am still fairly new to coding and learned about the basics of ASP.NET Identity. I have used ASP.NET Identity in past personal projects for User Authentication (Individual User Accounts) and Login. As I learn more about how an application should be structured and other coding guidelines, I question whether one should reorganize the code that ASP.NET Identity provides when User Authentication is provided. Should we?

For example, looking at the AccountViewModel class below other ViewModel classes are defined within it. I was under the impression that this was bad practice. Is it? Any examples of organizing the ASP.NET Identity code better? Are there any other authorization/authentication solutions I should learn or consider using instead of ASP.NET Identity?
