Only an Org administrator can set a user's default application.
Overview
Org administrators can set the user’s default application (Flows and/or IIP).
To set a user's default application:
Click Settings in Manager to display the Organizational Settings screen.
Scroll to the bottom of the Organizational Settings screen.
Click Set Default Application.
SnapLogic displays the Set Org Default Application dialog box:
Select the desired default application from the drop-down list.
If you create a user through IIP, it will be the default application for the user.
If the user had access to an application to which access was revoked and if it was the last enabled/logged-in application, the user will be redirected to the default application. Users will be able to select a default application from the user settings/profile from each of the applications.
If the user does not have access to an application they will be redirected to the sign-up page.
