Since your validation rules are different for create and edit. I would suggest creating two different models. One that handles create and one that handles edit.

public class CreateFoo
{
    [Required(ErrorMessage = "Password is required")]
    public string vcr_Password { get; set; }

    //other properties.
}

public class EditFoo
{
    [Required]
    public int Id {get;set;}
    //other properties that might be editable..    
}
