Android Panels - Kiosk Mode - Emergency shutdown of the Kiosk mode by Rest API
This article explains how to remotely or in emergency shut down the Kiosk mode, when an access password is lost or reset, without a need to change Android system settings.
1. Configuring a query in the Postman app
First, go to: https://www.postman.com/downloads/ , download the Postman app, and set up a user account (although this step is not strictly required). Then, go to File/Settings and set the ‘SSL certificate verification’ to off.

The following step is to create a query that will be sent to the device. Select the POST option and enter the command including the IP address and communication port, for example, https://192.168.1.130:5580/unlock. In the Authorization tab, select the Basic Auth option and provide username and password. Default credentials for authorization are: admin/password. Having provided the command and credentials, click the Send button and send the command to the device.
