Generate Your License
By default, when you install Nessus, your license is hidden and automatically registered. You cannot view this license.
However, if your Nessus Server is not connected to the internet (in other words, it is offline), you must generate a license. This license is unique to your Nessus product, and you cannot share it.
Your license is a text-based file that contains a string of alphanumeric characters. The license is created and based on your unique generated challenge code.
On a system with internet access (B), navigate to the Nessus Offline Registration Page.
Where prompted, type in your challenge code.
Example Challenge Code: aaaaaa11b2222cc33d44e5f6666a777b8cc99999
Next, where prompted, enter your Nessus activation code.
Example Activation Code: AB-CDE-1111-F222-3E4D-55E5-CD6F
At the bottom of the resulting web page, an embedded nessus.license file that includes the license text string appears.
- Next, Download and Copy License File (nessus.license).
