You can lock your ebook to a dongle, which means that the publication will not work if the correct dongle is not inserted.
The publication will check the dongle’s presence:
✔️ at startup
The publication will not open if the dongle is not inserted.
✔️ regularly during execution (if you wish): you can define the frequency of these verifications, every 30 seconds for instance.
If the dongle is not found, a nag screen pops up requiring insertion of the dongle in the 15 seconds. If the dongle is not inserted in time, the ebook exits.
➡️ If you want, you can set restrictions: limit the number of times your publication can be run, make your key expire after a given number of days or after a given date.
