Abstract: The disclosed technology teaches a method for customers of an organization to perform configuration at runtime for authentication journeys used by the customer's users, to simplify authentication trees, and to delegate configuration to the customer's administrators, wherein an authentication tree implements an authentication journey, the authentication tree including authentication nodes and edges connecting the authentication nodes. The method includes configuring an editable script and an authentication node used in the authentication tree in response to a user invocation of the authentication journey by executing a factory method that applies configuration parameters to the editable script and to parameters used to access an API.
