  TestBank is a fictional financial institution connector for exercising the
  Flanks Connect flow. Behaviour is driven by special trigger values entered in
  the credential password field and in the SCA challenge input; there is no
  separate sandbox base URL.

  Chain challenges by entering the corresponding special password on the
  challenge input field. No fixed test username/password pairs or separate
  sandbox host are published; TestBank runs against the production Connect flow
  using these reserved trigger strings.
