在ASP.NET核心身份中，如何在用户打开设置页面时询问密码？

services.AddAuthentication(options =>
{
    options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
})
.AddCookie(options =>
{
    options.LoginPath = "/Account/Login"; // 设置登录页面路径
    options.AccessDeniedPath = "/Account/AccessDenied"; // 设置访问被拒绝页面路径
});

[Authorize]
public class SettingsController : Controller
{
    // 控制器的其他代码
}

[HttpPost]
public async Task<IActionResult> Login(LoginViewModel model)
{
    if (ModelState.IsValid)
    {
        var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);
        if (result.Succeeded)
        {
            // 用户已成功登录，可以重定向到设置页面或其他需要身份验证的页面
            return RedirectToAction("Index", "Settings");
        }
        else
        {
            ModelState.AddModelError(string.Empty, "登录失败，请检查您的用户名和密码。");
        }
    }
    return View(model);
}
