  # Specify what grant flows are enabled in array of Strings. The valid

  # "implicit"           => Implicit Grant Flow
  # "password"           => Resource Owner Password Credentials Grant Flow

  #
  # If not specified, Doorkeeper enables authorization_code and
  # client_credentials.
  #
  # implicit and password grant flows have risks that you should understand
