Answer 1

Get user from UserManager by email.

var user = UserManager.FindByEmail(email);

Then use SignInManager's PasswordSignInAsync with user's Username

var result = await SignInManager
.PasswordSignInAsync(user.UserName,password,isPersistent,shouldLockout);

Or inside your SignInManager add this method (ASP.NET Identity discussion)

public async Task<SignInStatus> PasswordEmailSignInAsync(string email, string password, bool isPersistent, bool shouldLockout)
{
      var user =  UserManager.FindByEmail(email);
      return await PasswordSignInAsync(user.UserName,password,isPersistent,shouldLockout);
}

Then use it same as PasswordSignInAsync but with user email instead of usermane.
