In general, to use software protected by iLok, an iLok USB dongle or an alternative method such as iLok Cloud may be required. The need for a physical iLok device largely depends on the specific software and how the licensing is set up by the developer. Many software applications that utilize iLok protection require the USB dongle for authorization, enabling users to run the software on different machines without having to reauthorize each time.
However, some developers offer options for digital licensing through iLok Cloud, which allows users to authorize their software without the need for a physical dongle as long as they have internet access. It is always best for users to check the specific licensing requirements on the website of the software they are interested in to understand the options available to them regarding iLok protection. Users can usually find detailed information on the current web page of iLok.
