Hey Mike,
No, all of our licensing solutions are locked to the machine. This is by design. "Dongle type" licensing adds unnecessary expense for you and your end-users.
You'd be best using floating licensing for this use-case: https://wyday.com/limelm/help/licensing-types/#floating
In this case the end-user can move from computer to computer without ever having to plug in a random unknown dongle (avoiding security concerns altogether).
Let me know if that make sense.
