How does authentication work in ASP.NET Core middleware?

Can you explain how authentication works in ASP.NET Core middleware?

Sure! In ASP.NET Core, middleware is used to handle authentication by processing requests and responses. It checks if a user is authenticated before allowing access to certain resources.

What types of authentication can I implement?

You can implement various types of authentication such as cookie-based, JWT (JSON Web Tokens), OAuth, and OpenID Connect.

How do I set up cookie authentication?

To set up cookie authentication, you need to configure the authentication services in the Startup.cs file and specify the cookie options.

Can you provide a code example for setting it up?

Certainly! Here's a simple example:

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options => {
        options.LoginPath = "/Account/Login";
    });
