Entity Framework 1 to 1 / 1 to * - entity-framework

Question

I have this setup of classes:
public class User
{
public int Id { get; set; }
public string LoginName { get; set; }
public int CurrentPasswordId { get; set; }
public virtual ArchivedPassword CurrentPassword {get;set;}
public virtual ICollection<ArchivedPassword> UsedPasswords { get; set; }
}
public class ArchivedPassword
{
public int Id { get; set; }
public string Hash { get; set; }
public int UserId { get; set; }
public virtual User User { get; set; }
public virtual ICollection<User> Users { get; set; }
}
ModelBuilder.Entity<ArchivedPassword>()
.HasMany(e => e.Users)
.WithRequired(e => e.CurrentPassword)
.HasForeignKey(e => e.CurrentPasswordId)
.WillCascadeOnDelete(false);
ModelBuilder.Entity<User>()
.HasMany(e => e.UsedPasswords)
.WithRequired(e => e.User)
.HasForeignKey(e => e.UserId)
.WillCascadeOnDelete(false);
When i try to add a user and a password, ef can´t figure out the update order.
Is this a mapping Problem?

I am not expert on Database .But i think you can not make two different Foreign Keys for same tables.But you can success what you want as below code
public class UserContext : DbContext
{
public DbSet<User> Users { get; set; }
public DbSet<Password> Paswords { get; set; }
}
public class User
{
public int Id { get; set; }
public string Name { get; set; }
[NotMapped]
public Password Password
{
get
{
return Passwords.ElementAt(Passwords.Count - 1);
}
}
public virtual ICollection<Password> Passwords { get; set; }
}
public class Password
{
public int Id { get; set; }
public string Hash { get; set; }
public virtual User User { get; set; }
}
