I am learning how to implement user registration, login, logout flow.

I am using MVC ASP NET CORE (.NET 8)

I created app which has possibility to register users by email or with the help of third party OAuth providers (Google), but I am not really happy with the ending result, so I tried to find project examples with best practices which reveal how to implement following features:

1. User registration by email
2. User registration by third party AOuth provider
3. User login
4. User logout
5. User confirmation (in my case by email)

After my investigation I could not find project example with those features implemented in good way with clean code and best practices.

So I am here to ask help, maybe someone faced with hte same problem and got this example.
I belive stackoverflow will help me!
Thanks!

I tried to find best solution ways of my problem (implementing it by myself, find examples of implementaions), but I coud not.
