It is best to contact your supplier first, and have them provide your key information. Once you have that information, send along via email to firstname.lastname@example.org. We can then associate your email and your key, allowing you to manage the seat allocation directly.
We do not show the key in the User Interface, we have many customers that use LightBurn in schools, MakerSpace or in a shared environment where displaying could expose this private information to others.
those are security policies of Ligthburn staff, if i had well understood your issue, you have to complain with those who sell you the laser machine and installed LB on your pc, not with Ligthburn itself
