Some tips on giving digital privacy/security advice: if you tell people they absolutely need to do a long list of difficult and expensive things before they travel, people will nod and smile and then not do it at all. This is why my advice focuses on harm reduction and understanding trade-offs.
@evacide do you think the push against paper boarding passes is a push to make people bring unlocked smartphones into airports and through customs?
@bookandswordblog I couldn't say, but it is the thing that changes the most about my own travel experience when I need to be especially careful with my data and devices while crossing a border.
@evacide I will be flying internationally in April and will do my best to avoid using digital boarding passes. I don't plan to visit countries like Russia or the USA for the foreseeable.
