A free program for Android, by Marco Stornelli.
SecureTask is an application that lets you perform several tasks from your computer, using a secure connection. This tool requires special access, so it is not for everyone. You need to have the Device Administrator permission to install it.
The program can work on several devices. The app does not require root access, and it can be used on tablets. It is free, so there is no need to pay for it.
It is not a standalone program, it is a service that you can use from your web browser.
To start using it, you need to download the tool and install it on your device. After installation, you can start using it, with no extra steps.
