I would like to create a copy of a client’s site (that uses my GP license) to use as a staging site. The client has contracted a third party to develop a custom plugin for them and I want them to test on the staging site before deploying the plugin to production.
My worry is that this will expose my GP licence to this third party. Is there a way that I can safely create a copy of production without exposing my GP license?
the license key is obscured so the developer should not be able to extract that from your site.
If you want to be doubly sure simply delete the license key string in Appearance > GeneratePress and Save. It will simply stop the site from receiving updates.
