This guide is intended to help people who have already purchased software, but are for whatever reason unable to access their credentials, either temporarily or permanently. Gizmodo does not support software piracy. Further, this is general information, and you should proceed at your own peril.
If you follow through on every step listed here, you’re going to be pretty hard to find. But it’s still possible. And while being able to produce receipts for the software you’re using illegally will temper whatever punishment you receive, the fact is, you can still get in some serious trouble for pirating software—even software you already own. Caveat latro.
