Alternative Asp.NET Core Authentication Framework

Question

I have searched here as well as google, but couldn't find a clear answer. I am curious if there are any good alternative frameworks for handling authentication/authorization in the manner that Identity does for ASP.NET core.

The standard Identity Framework seems good except that I don't want to use Entity Framework and also would want to move this framework outside of my MVC project, but it seems that to accomplish this inside of Identity would be a large task.

For example, how does StackOverflow handle their authentication, (or any other large enterprise site)?

Answer 1

If you don't want to use default Identity, Microsoft has provided many ways to custom this. You can read in this article for using Cookie Authentication without Identity or Custom Policy-based.

So many Nuget libraries can help you to integrate with SaaS Authentication such as Auth0, AWS Cognito, etc.
