To protect your laptop when traveling, focus on the data first and the hardware second: turn on full-disk encryption, set a strong login, back up your files and keep the system updated. Then add sensible physical habits such as keeping the laptop with you and never leaving it unattended. If the worst happens, an encrypted and backed-up laptop is an inconvenience rather than a disaster.
How to protect your laptop’s data before you leave
A laptop can be replaced; your files, saved logins and email cannot always be. Preparing the data side at home is the most valuable thing you can do.
Turn on full-disk encryption
Modern operating systems include built-in disk encryption. When it is enabled, someone who steals the machine cannot simply read your files by removing the drive. Check that it is on, and store your recovery key somewhere safe that is not on the laptop itself, such as a password manager or a printed copy at home.
Use a strong login
Encryption is only as strong as the password guarding it. Use a long passphrase rather than a short PIN where possible, set the laptop to lock quickly when idle, and require a login after sleep. If your device supports a fingerprint or face unlock, treat it as a convenience on top of a strong password, not a replacement.
Update and back up
Install pending system and browser updates before you go, since updating on unfamiliar networks is inconvenient and slower. Make a complete backup too. Our guide to backing up your data before you travel covers how to do it properly.
Travel light with your data
Consider whether you really need everything on the laptop. Old documents, scans of identity papers and years of email archives are all at risk if the device goes missing. Remove what you do not need, or keep it in an encrypted cloud or external drive left at home. Some people also make a separate low-privilege user account for the trip.
Physical habits that make a difference
Most laptop losses are mundane: left on a train seat, forgotten at a security tray, or lifted from a cafe table in seconds.
- Keep it with you. Carry it in your hand luggage rather than checked baggage.
- Do not leave it unattended, even briefly, in cafes, lounges or coworking spaces. Take it with you to the counter or restroom.
- Use a plain bag. A padded sleeve inside a normal backpack draws less attention than an obvious laptop case.
- At security checkpoints, put the laptop through last and pick it up first, and keep your eyes on it.
- In hotels, use the room safe if there is one, or at least keep the laptop out of sight when you leave.
- In vehicles, never leave it visible in a parked car.
A cable lock can deter opportunistic theft in a coworking space, although it will not stop a determined thief. Treat it as one small layer, not a guarantee.
Working safely in public
Screens are easy to read over your shoulder. A privacy filter makes that harder, and choosing a seat with your back to a wall helps too. For networks, assume public Wi-Fi is untrusted: use HTTPS sites, a VPN and two-factor authentication on important accounts. Our hotel Wi-Fi safety tips apply nearly everywhere you connect away from home.
Be careful with unknown USB devices and public charging stations. Use your own charger in a mains socket whenever possible. Do not plug in a flash drive you have found or been handed.
When it is not in use, shut the laptop down or lock it, rather than leaving it sleeping with the session open. Turn off Bluetooth and file sharing when you do not need them.
A quick pre-trip checklist
| Task | Done? |
|---|---|
| Full-disk encryption enabled, recovery key stored safely | |
| Strong passphrase and short auto-lock | |
| System and apps updated | |
| Fresh backup made and tested | |
| Unneeded sensitive files removed | |
| Device-finding feature turned on | |
| Two-factor authentication active on email and key accounts |
What to do if it is lost or stolen
Have a plan before you need it. If the laptop disappears, act quickly and calmly.
- Use the built-in find-my-device feature, if it was enabled, to locate, lock or remotely erase the machine.
- Change passwords for your email first, then other important accounts, from another trusted device.
- Sign out of active sessions on your accounts and revoke the lost device’s access.
- Tell your employer straight away if it is a work laptop. Companies often have a procedure and may be able to wipe it remotely.
- Report the loss to the relevant authorities or transport operator where appropriate, since you may need a report for insurance. Check your policy’s terms for what it covers.
Do not try to recover a stolen laptop yourself. Pass any location information to the police instead.
Also think about your wider account security. A password manager and two-factor authentication make a lost laptop much less dangerous; see our password manager basics for a quick start.
Where to start
If you only have ten minutes, check that disk encryption is on, update the system, and make a backup. Then adopt the habit of never letting the laptop out of your sight. You will find more preparation guides in our Travel & Remote Work section.
Frequently asked questions
Is full-disk encryption enough to protect my laptop?
It protects your files if the machine is stolen, but only with a strong login password. You should also keep backups, updates and two-factor authentication in place.
Should I put my laptop in checked baggage?
It is generally safer in your carry-on, where you can watch it and where it is less likely to be damaged or lost. Check your airline's rules for devices.
Do privacy screen filters work?
They narrow the viewing angle so people beside you find it harder to read the display. They do not stop someone directly behind you, so seat choice still matters.
What should I do first if my laptop is stolen?
Change your email password from another device, then use find-my-device features to lock or erase it. Notify your employer if it is a work machine.
