What is KMS Activation?
KMS activation is a method of activating Microsoft products that are licensed in bulk, such as Office 2021. KMS activation requires a KMS host computer that runs a service that can activate other computers on the same network. The KMS host computer must have a KMS host key installed and activated. The KMS host key is a unique key that is assigned to your organization by Microsoft.
The computers that want to activate Office 2021 by using KMS must have a KMS client key installed. The KMS client key is a generic key that is preinstalled on all volume licensed versions of Office 2021. The KMS client key tells the computer to look for a KMS host computer on the network and request activation. The KMS host computer verifies the request and activates the Office installation if it is valid.
KMS activation has some advantages over other methods of activation, such as:
It does not require an internet connection or a phone call to Microsoft.
It can activate multiple computers at once without entering individual product keys.
It can automatically renew the activation every 180 days as long as the KMS host computer is available.
