Abstract: The disclosed technology teaches integrating theme management of user interfaces that implement an authentication journey for hosted services, receiving user input and responsively configuring a switch block node used in the journey. A first configured control of the node selects an authentication-related state variable to set a switch and a second configured control specifies alternative settings. Also receiving user input and responsively composing a script used in the node to process the state variable and select among the switch settings, responsive to the state variable, and receiving user input and responsively creating a visual branding theme. Further included is receiving user input and responsively composing a directed graph in which nodes that implement the authentication journey are connected, applying the themes to named theme nodes, positioning and connecting the switch block node to subsequent named theme nodes, to which the switch block node alternatively directs a flow of the journey.
