Dongle protection: high security for your Excel spreadsheet

You can lock your Excel workbook to a dongle, which means that the workbook will not work without the correct dongle plugged in. This dongle protection is a powerful and strong security feature provided by XLS Padlock to Excel users.

The dongle protection requires the physical presence of the dongle to open the workbook

The workbook will check the dongle’s presence:

→ at startup
The workbook will not open if the user has not their dongle plugged in.

→ regularly during execution (if you wish): you can define the frequency of these verifications, every 30 seconds for instance.
Thus, without the dongle found, a nag screen pops up requiring insertion of the dongle in the 15 seconds. If the dongle is still not available in time, the workbook exits.

Add restrictions to the dongle

You can also set restrictions: limit the number of times your Excel workbook can be run, make your key expire after a given number of days or after a given date.

Last but not least, remote update of dongles is handled too: remotely upgrade the dongles already provided to your customers by extending restrictions such as new expiration date or usage count.
