Cookie-based authentication?

Q: Cookie-based authentication?

Short answer: Used in traditional MVC apps for session-based auth. services.AddAuthentication(CookieAuthenticationDefaults.Authenticati onScheme) .AddCookie(options => { options.LoginPath = "/Account/Login"; }); On login: await HttpContext.SignInAsync(principal); Cookies are stored in the browser and sent with each request. Real-world example (ShopNest) A ShopNest checkout request flows through middleware, hits a minimal API or controller, uses scoped services, and returns ProblemDetails on errors. Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
