Web Server Applications use Confidential Clients and require a Secret for authorization. The following steps describe how to reset a Client Secret. (We recommend that you rotate the Client Secret periodically).
In the Developer Portal, navigate to My Apps tab and select the Team from the drop-down menu. This opens the My Apps page showing the list of Apps created for the selected Team.
Click on Configure button for an App. This opens the App info to show the details of the selected App.
Click the Clients tab on the left pane.
Click the Configure button on the right side of the row that contains the Web Server Application Client, whose secret needs to be reset.
Click Reset Secret button as shown.
Click Confirm. This will generate a new Secret that you can copy using the copy icon on the popup and save for future reference.
