Access key for staging sites

I have a subscription to Cleantalk and an access key which I’m using on my live site. I also have a separate site which I use for development which mirrors the configuration of my live site.

However I’m not able to make changes to the Cleantalk configuration as I don’t have an access key for this site. Is it possible to use the same access key as on the live site? Or is there some other key I can use in order to run Cleantalk in a test environment?
