2nd question: When crossing borders between countries, one can be forced to open your phone, etc. But having touchID or faceID disabled can make it harder for "them" to get into your phone without your password. If one carries Yubikeys across a border, does that make your phone less safe? Does it make your online accounts that are 2FA less safe even if your passwords are not on the phone? Any thoughts about how Yubikeys might make one's online security in jeaporady when crossing borders? Thx
