In the next months I’m going to travel abroad with my Ledger Nano S. I’ll visit most of the EU countries, Russia, China, Brazil, U.S. and Canada. I’m an EU citizen.

I would like to know which is my right to refuse to unlock my Ledger whether I’m intimated to do so by a custom officer.

As far as I know as an EU citizen in the EU I can refuse to unlock my devices without violating any law.
