Upon entering the terminal, you'll need to show your cruise documents and go through a security line. You will need to pass through an x-ray machine and have your carry-ons scanned, but the process is not as rigorous as at the airport. (You likely won't need to remove your shoes, for example.)

Yes, cruise ship security is remarkably similar to airport security and is extremely thorough to ensure the safety of thousands of passengers in a confined environment. Before you board, you must go through a terminal security screening, where your carry-on and checked luggage are X-rayed for prohibited items like weapons, illegal drugs, and high-wattage electrical appliances (like kettles or irons). You will also pass through a metal detector or body scanner. Crucially, cruise lines are very strict about identification; you must present a valid passport or, for some "closed-loop" cruises from the US, a government-issued birth certificate and ID. Every time you re-board the ship at a port of call, you must again pass through a security checkpoint and scan your ship ID card, which displays your photo to the security officer on their screen. Many lines also utilize facial recognition technology for faster embarkation. In 2026, many ships also conduct behind-the-scenes checks, such as using canine units for narcotics or screening for excessive quantities of alcohol, which is often restricted according to the specific cruise line's "corkage" policy.
