@lechindianer Scary Indeed. I am not going to visit any country that demand my device and that I unlock it for them to peruse at their leisure. At least not by choice.
I'm thinking about getting a travel phone with exactly nothing in it, and brining that on trips. Should be about as helpful to the border folks as a wet wad of paper. ?
They can't coax any passwords of relevancy out of me either, as I genuinely don't know any anymore. Password managers for the win!
