What is a license key?

A license key is a way to make sure that only the correct user has access to this licence.  This means installing and also using the correct license, the key can come in either characters or numbers that must be validated when attempting to use the software for the first time.  Licensing can change depending on the license you purchase but it is important to note that there is a difference between a "license" and a "license key", a "license" is the license itself which needs to be purchased for the businesses need & the "license key" is to ensure the "end user" can access the correct license.
