Invalid login attempt in MVC - asp.net-mvc

Question

I am currently changing the default template of MVC5 project (with identity). When I first time register and login, all goes well. But when I made some changes like project at default level stores UserName as Email. But when I make change it to store UserName as from Form then it gives 'Invalid' login attempt. Can anyone tell me that where I am going wrong. Either I have to make changes at any other places if yes then where?
Here are my register function:
Before:
var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
I have changed this line to this:
var user = new ApplicationUser { UserName = model.usrName, Email = model.Email , PhoneNumber=model.Contact};
And my login function is as it comes in default. like,
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
if (!ModelState.IsValid)
{
return View(model);
}
// This doesn't count login failures towards account lockout
// To enable password failures to trigger account lockout, change to shouldLockout: true
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
case SignInStatus.Success:
return RedirectToLocal(returnUrl);
case SignInStatus.LockedOut:
return View("Lockout");
case SignInStatus.RequiresVerification:
return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
case SignInStatus.Failure:
default:
ModelState.AddModelError("", "Invalid login attempt.");
return View(model);
}
}
Now, can someone please tell me where i am wrong?

Answer 1

If you want to change UserName from model.Email to model.usrName, you have to use model.usrName in your Login function. Like this:
var result = await SignInManager.PasswordSignInAsync(model.usrName, model.Password, model.RememberMe, shouldLockout: false);
Because UserName and Password fields are default unique parameters to login. So it wants to complete login operation with UserName field.
