Create Individual User Accounts retroactively asp.net core 2 - authentication

I have created a web application using .net core 2. When I set it up I chose no authentication. Now I would like to add individual user authentication. Is this possible once the application has been setup? Maybe a command in the pm console?
I can make another project and select authentication. Is there a list of files that I can copy over to my existing web site?

It is a little late but maybe it will help other people:
Microsoft Documentation Security
It covers scaffolding Identity in ASP.NET Core projects. More precisely:
Scaffold identity into an empty project
Scaffold identity into a Razor project without existing authorization
Scaffold identity into a Razor project with authorization
Scaffold identity into an MVC project without existing authorization
Scaffold identity into an MVC project without existing authorization
Scaffold identity into an MVC project with authorization
Create full identity UI source

Can ASP.NET Core Identification & Authorization map to Active Directory?

Reading this it looks like the ASP.NET Core I&A system can not use ActiveDirectory. And that same page says for the API part of the web service, that should use ActiveDirectory.
Since I don't want users to have to create 2 logins, is there any way to point the ASP.NET Core I&A system to call down to Active Directory?
And if not, is there a good example about how to use ActiveDirectory for the forms part of an ASP.NET Core app?

dotnet core 3.1 angular identity server 4 views

I was playing with a new project using dotnet core 3.1, angular and individual user accounts.
After create the project I added scaffolded items for Identity.
All views are using MVC.
Is there Angular views version for this?
When we are using IdentityServer as an identity provider. We are using different approach as Individual User Accounts. So, identity provider service will handle all operations such as create, update, change password, etc.
This is the reason of why we don't have same things in Angular and IdentityServer. But you can use Skoruba project, which handle a lot of requirements.

How do I revert to controller based identity and authentication in .NET Core 2.1

I would like to use a Controller based Identity with .NET Core 2.1. I would like to scaffold the UI but the scaffolder creates Razor Page based identity. I would like to use controllers instead of Razor Pages. Is it possible to scaffold this?
I found that creating a new project and choosing the.net core V2 with authentication will create the controller based authentication vs the razor one.

Host ASP.NET Core in a Windows Service with Identity framework

Looking at Host ASP.NET Core in a Windows Service, I downloaded the sample and got it to work fine.
How would I add ASP.NET Core Identity to this sample window service ? it seems using a windows service is the recommended way to host an ASP.NET Core app on Windows but I can't find any information on adding Identity ..
Thanks!
IT's not as simple as just adding it. I would suggest, you create a new projekt (from template) with identity and then migrate those implementations to your project.
In core 2.1, you could add a library with identity and yous scaffold the pages you need to edit. Adding Identity in core 2.1

ASP.NET Core project templates are missing Models folder if project is created with Windows Authentication mode selected

On our Windows 8.1 machine when we create an ASP.NET Core project using any of the two templates ASP.NET Core Web Application (.NET Core) orASP.NET Core Web Application (.NET Framework) and select authentication mode as Windows Authentication the Models folder does not get created as shown in the image below. Whereas, if we use the default authentication Individual User Account the Models folder gets created. Why ASP.NET Core projects does not create Models folder when using Windows Authentication? I checked on the explorer view of the project, as well, and no such folder is there.
No Models folder:
Because you have chosen NO AUTHENTICATION while creating your project. Change NO AUTHENTICATION to INDIVIDUAL USER ACCOUNT.
See this article
Why doesn’t MODELS folder gets created automatically in solution explorer while creating new project in MVC 5 or ASP.NET Core 1.0?
