If you use the token, it works with private tabs and VPNs. I don’t share my account, but I do use those things and I’ve never had an issue. I don’t see how they could know the difference with a shared account vs multiple devices. I search from my phone, my work PC, my vpn’d laptop constantly all day. They might have some system that hashes your IP, and if there’s more than 4 matching hashes in an hour throw a flag.
Is your original question a privacy focused one, or a service level question?

Service question. My concern is getting flagged inaccurately since they offer the duo plan.
