Fragment from file auth.ex

  def authenticate(email, encrypted_password) do
    query = Ecto.Query.from(u in User, where: u.email == ^email)
    |> limit(1)
    Repo.one(query)
    |> check_password(encrypted_password)

    case user do
      nil -> Bcrypt.dummy_checkpw()
      _ -> Bcrypt.checkpw(password, user.encrypted_password)
    end
  end
