  # authenticating a user, both parameters are required. Remember that those
  # parameters are used only when authenticating and not when retrieving from

  # given should be a request method and it will automatically be passed to the

  # ==> Configuration for :encryptable
  # Allow you to use another encryption algorithm besides bcrypt (default). You can use
  # :sha1, :sha512 or encryptors from others authentication tools as :clearance_sha1,
  # :authlogic_sha512 (then you should set stretches above to 20 for default behavior)

  # to be supplied on each request. Useful if you are using the token as API token.
  config.skip_session_storage << :token_auth

  # ==> Scopes configuration

  # "users/sessions/new". It's turned off by default because it's slower if you
  # are using only default views.

  # The default is true, which means any logout action will sign out all active scopes.
  # config.sign_out_all_scopes = true

  # ==> Navigation configuration
  # Lists the formats that should be treated as navigational. Formats like
  # :html, should redirect to the sign in page when the user does not have
  # access, but formats like :xml or :json, should return 401.
  #
  # If you have any extra navigational formats, like :iphone or :mobile, you
