so you can pass it on to who ever you like along with the serial number.
You do really need to read the licence terms to be sure of that.
I know of many examples where transfer rights are strictly controlled, not least because generally you buy rights (a licence) to USE software, not to own it.
And manufacturers, especially of more expensive software, put considerable controls in place to ensure compliance.
This often involves, registration, activation, tying to an account via linked to a username and/or email address etc. etc.
At one extreme much "OEM" software has no transfer rights at all and must stay on the same physical computer.
For example I have some expensive diagnostic software that does allow limited relocation to another PC, but only once if I recall correctly, and via a fairly tedious process. (it also requires some hardware as well, though not a "dongle" in the traditional sense))
