Fresh account or your main for NBA 2K27 hack testing?

Pretty simple question. If you try any kind of third party tool in 2K27, do you do it on your main or on a separate account?

The obvious point is that your main is the one with all your progress, so it carries the most to lose. But plenty of people do it anyway. What’s your setup and why? And if you use a second account, do you bother with anything else to keep it separate from your main? We list game accounts and an HWID spoofer if you need either.
