Hello gentlemen,
It is all very clear on iLoks information pages, and there's nothing I can add to their description.
You can also check out the iLok support page with a lot of FAQs.
When using an iLok key, ZDT and TLC on an iLok 3 is the best combination to keep the licenses on your iLok safe and definitely worth the investment.
Moving your licenses to the cloud when you are traveling (or not working) is another option.
Using the cloud without the key is another option.
We have not published any numbers regarding the cost of replacement licenses on a lost/stolen iLok key yet.
With eLicenser, the cost was 50% of the full price of the replacement license.
It is easy to prevent these costs if you are a "mobile musician" and in danger of losing the key, with the Vienna Protection Plan that is still available at this point.
Best,
Paul
