Why Digital Safety Matters When You Travel
Travel puts you in contact with unfamiliar networks, unfamiliar machines, and situations where your guard may naturally be lower than at home. Public Wi-Fi at airports, hotels, and cafes is a convenience — but it's also a shared environment where, without the right precautions, data you send can potentially be visible to others on the same connection. Physical risks compound this: a stolen phone or laptop doesn't just cost money, it can expose account credentials, financial information, and personal documents.
The good news is that digital safety for travelers doesn't require technical expertise. A handful of settings changes and habits — most of which take minutes to set up — dramatically reduce your exposure. This guide walks you through those steps in order of priority, starting with what to do before you leave home. For a broader foundation, see our beginner's travel safety overview, which covers physical and situational safety alongside the digital.
Never Bank on Public Wi-Fi Without Protection
Accessing your bank, email, or any account containing sensitive data over an unsecured public network is one of the highest-risk habits travelers have. On open networks, other users on the same connection may be able to intercept unencrypted traffic. Always use a VPN or wait until you're on a trusted, password-protected network before logging into financial or personal accounts.
Understanding how travel scams are structured is also worth your time — digital deception and phishing attempts are increasingly common targeting travelers in transit.
What You'll Need Before You Start
No specialized hardware is required. What matters most is access to the settings on your own devices and a few minutes to configure them properly before you depart. The tools below are worth considering:
VPN (Virtual Private Network) App
Encrypts your internet connection so your data is not readable by others on the same network.
Password Manager
Stores complex, unique passwords for each account so you don't reuse credentials that could be compromised.
Two-Factor Authentication (2FA) App
Generates a one-time code required alongside your password, making account takeover much harder.
Mobile Data Plan or International SIM
Provides a private, carrier-based connection as an alternative to untrusted public Wi-Fi.
What you will need
Step-by-Step: Protecting Your Data on the Road
Work through these steps before departure where possible. Steps 1 through 5 are best completed at home on a trusted network. Steps 6 and 7 apply both before and during travel.
Enable Screen Locks and Device Encryption
Before you pack your bag, go into your device settings and confirm that a strong screen lock — a PIN, password, or biometric — is enabled on every device you're bringing. On most modern smartphones and laptops, full-device encryption can also be switched on in the security settings. Encryption scrambles the data stored on your device so it cannot be read without your credentials, even if someone physically removes the storage.
Turn On Two-Factor Authentication for Key Accounts
Log in to your most important accounts — email, banking, and any account linked to payment information — and activate two-factor authentication (2FA). With 2FA enabled, logging in requires both your password and a one-time code sent to your phone or generated by an authenticator app. This means a stolen password alone is not enough for someone to access your account.
Install and Configure a VPN Before Departure
A VPN (Virtual Private Network) creates an encrypted tunnel between your device and the internet, so that data passing over a public Wi-Fi network cannot easily be read by others on the same connection. Download and test a reputable VPN app at home before your trip — some VPNs require account setup that is easier to complete on a familiar network.
Minimize What You Carry Digitally
Consider which apps and accounts you actually need access to during your trip. Log out of financial accounts or apps you won't use, and remove sensitive apps from devices that might be more likely to leave your possession (such as a shared tablet). The less sensitive data that's accessible on your device, the less is at risk if something goes wrong.
Enable Remote Lock and Wipe on Your Devices
Most smartphones and laptops allow you to remotely lock or erase your device if it's lost or stolen. On iOS, this is managed through the Find My feature; Android devices have a similar Find My Device function; laptops vary by operating system. Enable these features before you travel and note how to activate them from another device or a web browser in an emergency.
Stay Alert at ATMs and Payment Terminals
When withdrawing cash or paying by card, take a moment to examine the card reader before inserting your card. Look for anything that seems loose, misaligned, or added on top of the original hardware. Cover the keypad with your free hand when entering your PIN as a basic precaution. Prefer ATMs located inside banks or well-lit, monitored locations over standalone machines in quieter spots.
Back Up Your Data Before You Leave
Create a fresh backup of your devices before your trip. If a device is lost, stolen, or damaged, a recent backup means you won't permanently lose photos, contacts, or important documents. Store backups in a secure cloud location or on an encrypted external drive kept separately from your devices. For document backups specifically, see our guide to passport copies and cloud backups for detailed steps.
Set Up Security Features Before You Leave Home
Configuring two-factor authentication, device encryption, and remote-wipe features is far easier before you travel than during a stressful trip. Spend 30 minutes at home going through each account and device so these safeguards are already active when you need them most.
Staying Vigilant During Your Trip
Good digital habits are ongoing, not a one-time checklist. During travel, keep your VPN running on public networks, avoid leaving devices unattended in public spaces, and be skeptical of any prompt asking you to enter account credentials on an unfamiliar device or network. If you suspect a device has been compromised, change your passwords from a trusted connection as soon as possible and notify your bank if financial accounts may be affected.
Pairing digital awareness with physical situational awareness makes both more effective. Our article on reading your surroundings in unfamiliar cities covers the physical side of staying alert. For payment-specific risks, weighing cash versus cards while traveling offers a balanced look at each option's trade-offs.
Inspect ATMs and Card Readers Before Using Them
Skimming devices — small hardware attachments criminals place over legitimate card slots — have been documented at ATMs and point-of-sale terminals worldwide. Before inserting your card, gently tug the card slot to check for loose overlays, and cover the keypad when entering your PIN. If anything looks unusual, use a different machine and report it to the venue.
