Being an important feature of XLS Padlock, activation keys offer a powerful licensing system for Excel workbooks: you can require end users to activate the secure application with an activation key before they can access your protected workbook. Activation keys can have expiration date or limited number of runs, and they can also be hardware-locked: in that situation, a key will only work on a given computer.

In addition to XLS Padlock’s built-in “Key Generator”, we provide a stand-alone key generator (that can output thousands of keys at once) and a key generator SDK so that you can make keys directly on your server/website.

Finally, it is possible to work with online activation and validation features: they allow a remote control on how your users access your workbook.

To get started with activation keys, please take a look at the "How to set up activation keys" tutorial.
