For Asprova and Asprova NLS/DS, we recommend online license activation, which requires less operational effort.
With online license activation, license information is managed over the internet. This provides the following benefits:
* No need to enter Magic Numbers manually
* License information is automatically updated when you renew your maintenance contract
* License information is also automatically updated when you add modules or options
For instructions on setting up online license activation, please see the Knowledge Center.

If you do not use online license activation, you can use the method of storing license information on a protector. Protectors come in two types: the “USB Protector” (a hardware key) and the “e-Protector” (a software key). With this method, you need to apply a Magic Number to update your license whenever you renew your maintenance contract or add modules or options.
A Backup Protector is also available for emergency use if a protector fails.
For details on each protector, please see below.
