While traveling, the best place to store your passport depends on whether you are "in transit" or have reached your destination. When moving through airports or borders, keep it in a secure, zipped pocket on your person or in a dedicated "neck wallet" or "money belt" hidden under your clothes. Never put your passport in a checked bag or an outer "easy-access" pocket of a backpack where it could be easily swiped. Once you arrive at your hotel, the safest place is the in-room electronic safe. If your room doesn't have one, keep it locked inside your hard-shell suitcase using a TSA-approved lock. It is generally recommended not to carry your physical passport with you while sightseeing; instead, carry a high-quality paper photocopy or a digital photo on your phone for identification purposes. This prevents the nightmare scenario of losing your primary travel document to a pickpocket or accidental misplacement while exploring a new city. Always keep a backup photo of your passport in a secure cloud-based folder (like iCloud or Google Drive) in case of emergencies.
