Registering Fortiauthenticator to get licensen file?

Hi,

So far all the Fortinet products we have bought have been easy to register. Just login at Fortinet, use the serial no to register and voila.

But, after installing Fortiauthenticator i get the serial no :   FAC-VM0000000000 and I can use it to register my copy and get the license file.

Should the registering be done in some other way or?
