Thanks to XLS Padlock, you can lock your Excel workbooks to a USB stick or dongle, which means that the compiled workbook application will not work if the correct USB device or dongle is not inserted. The Excel workbook application will check the USB stick or dongle’s presence at startup. It can also check for dongles regularly during execution if you wish.
If you want to use this protection, tick the option “Link the application to a dongle or a USB stick” and select the device model you have.
