twofactor authentication is outofbox feature so can we implement the twofactor authentication in the accountconntoller/login(postmethod) like.
when the user is login to the application can we check user is eligible for the RequiresTwoFactor and then implement the customziation for the two factor authentication.
var user = await _signInManager.UserManager.FindByNameAsync(model.Username);

// validate username/password using ASP.NET Identity
var result= await _signInManager.CheckPasswordSignInAsync(user, model.Password, true));
if (user != null && result.Success)
{
//credential based authentication

}
else if (result.RequiresTwoFactor)
{
//can we write our twofactor authentication here.
}
