| Ultimately, when you choose to enter a duress PIN that will wipe your device, you have to recognize that choice may have legal consequences. I don't like the amount of power our government has at the national border when it comes to detaining and pressuring citizens, but our Constitution explicitly grants it at least some of the power it now exercises in that context. If your threat model includes US state actors at the national border, then your security practices need to account for the confiscation of your device at that border without requiring you to willfully wipe the phone and (in the eyes of police and prosecutors) destroy evidence. That means: 1. Don't travel with anything you can't afford to lose on device. This means setting up travel-specific password managers and hardware keys for a subset of your accounts that you absolutely need to access while abroad, and being prepared to reset those passwords and disable those hardware keys very quickly once home. 2. Review past legal cases against travelers and identify what behaviors the government considers worthy of prosecution or harassment. Your secure setup must function without needing you to engage in those behaviors, even if it is less convenient as a result. This isn't perfect, as the government may decide some new behavior is prosecutable. 3. Consult with a lawyer and review your security procedures from a legal standpoint. All of the above is technical and practical advice, not legal counsel and no substitute for it. We Americans are fortunate to carry powerful passports and enjoy relatively easy international travel but, for better or worse, that velvet glove covers an iron fist we would be foolish to forget or ignore. |
