defmodule AuthShield.Credentials do
  @moduledoc """
  Credentials are means to proof that an identity is valid
  in authentications.

  There are multiple types of credentials and we implements
  three of them.

    - password (An sequence of digits that only the user known's);
    - pin (An code of 4 or 6 digits that usually are only numbers);
    - totp (An time based code generated in other factor or device);

  This module provides an interaface that delegates to the specific credential functions.
