Protecting your passport involves a "defense-in-depth" strategy that guards against both theft and environmental damage. First, always use a RFID-blocking passport cover to prevent digital skimming and to keep the physical pages dry and crisp. When on the move, a money belt or an "under-clothing" pouch is significantly more secure than a backpack or purse, which can be easily snatched. When you arrive at your destination, the best practice is to lock your passport in the hotel room safe and carry a high-quality physical photocopy or a digital scan on your phone instead. In 2026, many countries accept digital versions for routine ID checks, though you still need the original for border crossings. Avoid leaving your passport in "hidden" spots like under a mattress or in a suitcase, as professional thieves know to check there first. Additionally, keep a "backup" digital copy in a secure, encrypted cloud drive like iCloud or Google Drive so that if the physical book is lost, you have all the necessary numbers and details to expedite a replacement at the nearest embassy.
