I have more than one iLok key. Is there a way to combine authorizations onto a single key to free up a USB port?
Yes. You can move authorizations from any iLok Key in your iLok account to any other iLok key on that account. You can arrange your licenses in anyway you like on your multiple iLoks. If you wish to use multiple iLoks, purchasing a powered USB hub will allow you to employ multiple iLok Keys if you do not currently have additional USB ports available on your system.
