Travel Cybersecurity: 20 Ways to Stay Safe Online Abroad

Travel pulls you out of your usual routines. You join unfamiliar Wi-Fi networks, charge your phone wherever you find an outlet and pull out your laptop in crowded terminals, often while tired and in a hurry. That’s when small security slips happen.

Good travel cybersecurity comes down to a few simple habits: prepare your devices before you leave, be choosy about the networks and chargers you use, keep your gear close and know what to do if something goes missing. None of it requires technical skills.

Below are 20 practical cybersecurity tips for travelers, grouped by when you need them, plus a quick checklist for your next trip.

Before you go

Most of the work happens at home, on a network you trust, with time to spare.

1. Update your devices and apps

Install the latest updates for your phone, laptop, browser and apps before you leave, since updates fix security flaws attackers look for. If a pop-up on hotel or airport Wi-Fi says you must install an update to continue, close it and update through your device’s settings or app store instead.

2. Back up your data

A recent backup means that if a device is lost, stolen or damaged, you lose the hardware, not your photos and files. Back up to a cloud service, an external drive or both, and check that the backup finished. If you use a drive, leave it at home rather than in the same bag as your laptop.

3. Turn on two-factor authentication and save backup codes

Two-factor authentication (2FA) asks for a second proof, such as a code from an app, on top of your password, so a stolen password alone isn’t enough. Turn it on for your email, banking and social media at a minimum.

Travel adds a catch: if you switch to a local SIM, codes texted to your home number may not reach you. Authenticator apps and passkeys don’t depend on text messages, so they’re more reliable abroad. Save each account’s backup codes too.

4. Use a password manager

A reputable password manager creates and stores a strong, unique password for every account, so one leaked password can’t unlock the rest. Most will only fill in a password on the site it was saved for, which helps you spot look-alike phishing pages. It also makes changing passwords quicker if something goes wrong.

5. Turn on device tracking and remote wipe

Apple’s Find My and Google’s Find Hub (formerly Find My Device) let you locate, lock and erase a lost device from another device or a web browser. On iPhone, check Settings > [your name] > Find My; on Android, search your settings for Find Hub or Find My Device. Windows laptops have a similar Find my device setting. Give every device a strong passcode, and consider extra theft protections such as Stolen Device Protection on iPhone.

6. Travel with less data

The less you carry, the less you can lose. Leave devices you don’t need at home, move sensitive files you won’t need off your laptop, and sign out of accounts you won’t use on the trip. Border checks in some countries can include device inspections, which is one more reason to travel light.

7. Install and test your VPN before you leave

A VPN encrypts your traffic so the owners of the networks you use along the way can’t read it. Install it on every device you’re bringing and test it at home, because VPN apps can be harder to find in some countries’ app stores. Our VPN setup guide covers every major platform, and these quick tests show whether your VPN is working.

8. Check local laws on VPNs and encryption

VPNs are legal in most countries, but a few ban them or allow only government-approved services, and some restrict certain encryption tools. Rules change, so check your government’s official travel advice for your destination. Our guide to whether using a VPN is legal covers the details.

9. Consider an eSIM or local SIM

Your own mobile data means you don’t have to depend on public Wi-Fi. A travel eSIM, a digital SIM you download rather than insert, can often be set up before you leave and switched on when you land, as long as your phone supports eSIM and isn’t locked to your carrier. Buy from a reputable provider, and use your phone’s hotspot to get your laptop online.

In transit

Airports, stations and planes combine shared networks, public chargers and crowds.

10. Be careful on airport Wi-Fi

Anyone can set up a hotspot with a convincing name like “Airport Free WiFi,” a trick sometimes called an evil twin. Check the official network name on airport signs or at an information desk before joining, and turn on your VPN as soon as you’re connected. Our guide to the real risks of public Wi-Fi explains what can go wrong.

11. Charge from your own adapter or a power bank

In theory, a tampered public USB port or cable could push malware to a phone or pull data from it while it charges, an attack known as juice jacking. Confirmed real-world cases appear to be rare, so it’s a low-probability risk, but one that’s cheap to avoid: plug your own charger into a power outlet, carry a power bank or use a charge-only cable. If your phone asks whether to trust a device or allow file access while you’re only charging, decline.

12. Turn off Bluetooth and auto-join when you don’t need them

Every wireless connection you leave open is another way in. Turn off Bluetooth when you’re not using it, and set AirDrop (on Apple devices) or Quick Share (on Android) to receive from contacts only. Stop your devices from automatically joining open Wi-Fi, and “forget” public networks after use, since a fake hotspot can copy a network name your device already trusts.

13. Watch for shoulder surfing

Shoulder surfing is simply someone reading your screen or watching you type, and planes, trains and lounges make it easy. Sit with your back to a wall when you can, consider a privacy screen filter for your laptop, shield your PIN at ATMs and use face or fingerprint unlock instead of typing your passcode in public.

At your destination

Once you arrive, the risks shift to shared networks, shared equipment and your belongings.

14. Treat hotel Wi-Fi with care

Hotel Wi-Fi is shared with every guest, often with one password for the whole building, so treat it like any other public network. Confirm the exact network name with the front desk, then turn on your VPN before doing anything sensitive. For banking, your phone’s mobile data or hotspot is often the safer choice. When you check out, tell your devices to forget the network.

15. Avoid shared business-center computers for logins

Lobby and business-center computers are used by many strangers, and you can’t know whether one has malware or a keylogger, a program that records everything typed. Don’t log in to email, banking or other important accounts on them. To print a boarding pass, ask whether you can email it to the front desk instead. If you did sign in somewhere shared, sign out, close the browser and change that password later from your own device.

16. Clear your data from rental-car infotainment systems

When you pair your phone with a rental car, its dashboard system can store your contacts, call history, messages and destinations, which the next driver may be able to see. Decline requests to sync contacts or messages if you don’t need them. Before returning the car, delete your phone from the paired devices list in the system’s settings and clear saved navigation history, or use the system’s reset option if it has one.

17. Keep your devices physically secure

Often the bigger risk isn’t a hacker but a moment of distraction. Keep your phone and laptop in sight at security checkpoints, don’t leave them on cafe tables or in a parked car, and use your room’s safe or carry them with you. Set screens to lock automatically, and turn on your laptop’s built-in disk encryption (FileVault on a Mac, or device encryption or BitLocker on Windows) so a stolen laptop doesn’t mean stolen files. Most modern phones encrypt their storage automatically once you set a passcode.

If something goes wrong

If a phone or laptop goes missing, act quickly, in this order: secure the device, then your accounts, then your money and phone number.

18. Lock and erase the device remotely

From another device or a web browser, sign in to Find My or Find Hub and mark the device as lost. This locks it and can show a contact message on the screen. If you don’t expect to get it back, erase it remotely. Depending on the device, erasing may stop you from tracking it, so lock it first. Report a theft to local police as well, since insurers often ask for a report.

19. Change your key passwords

Start with your main email account, because it can be used to reset almost everything else, then move on to banking, your password manager and social media. Use each service’s security settings to sign the missing device out; most major services list the devices signed in to your account.

20. Contact your bank and mobile carrier

Call your bank and card issuers to freeze or replace cards, including any stored in a mobile wallet on the device. Then ask your mobile carrier to suspend your SIM or number. That stops someone from running up charges and from receiving the text-message codes that protect your accounts.
