How to apply ASP.NET Identity in layered architecture?

Question

ASP.NET

Good afternoon, colleagues.
I use building an application based on layers:
1) Data Access Layer (Repository CRUD (Generic))
2) Business Logic Layer (Services for each entity, etc.)
3) UI Layer (Web API or Web)
I would like to fasten authentication and authorization by tokens (providers Facebook, Google, etc.)
Looked at this article - metanit.com/sharp/mvc5/23.10.php I think this is some kind of garden.
Tell colleagues how to do authorization in this architecture now? (an example in which I want to apply authentication and authorization by tokens - https://github.com/itprodavets/Telerik.Kendo.UI)
Thanks in advance!

Answer 1

What is your problem? Can't register a user? Can't authorize it?
You have a simple three-link. By and large, above the third point, your system is no longer particularly interested in tokens and authentication.
