Protecting Your Laptop in Cafes and Coworking Spaces

Two kinds of risk

A laptop in a cafe or coworking space faces two separate problems. The first is physical: it can be stolen, or someone can look at it while you are away from your seat. The second is digital: you are using a network you do not control, near people you do not know.

Of the two, physical loss is usually the more likely. A stolen laptop is a very common travel mishap, and what matters is what a thief can reach once they have it. Most of the useful advice below aims at making a lost laptop an inconvenience instead of a crisis.

Protect the device itself

Do not leave it unattended, even briefly. Stepping away to order a drink or take a call is when many thefts happen. If you cannot take the laptop with you, ask someone you know to watch it, or pack it away. At a coworking space with lockers, use them.

Choose your seat. A spot with your back to a wall, and the screen facing away from the room, makes it harder for people to look over your shoulder or walk off with something unnoticed. Avoid seats near doors or windows where a quick grab is easy.

Consider a cable lock. Some laptops have a security slot for a cable lock. It will not stop a determined thief, but it deters opportunists. Whether it is worth the bother depends on how often you work this way.

Keep it close in transit. Keep the bag in your lap or between your feet, and avoid leaving it hanging on a chair. A plain bag draws less attention than one that advertises a laptop inside.

Mark and record it. Note the serial number somewhere other than the laptop, and keep proof of purchase. Insurers and police often ask for both.

Make a stolen laptop less damaging

If the worst happens, these steps limit what the thief gets.

1. Turn on full-disk encryption. Most current systems include it. With the drive encrypted and a strong sign-in password, the files are generally unreadable without the password. Check your system’s settings for the option, and keep your recovery key somewhere safe and separate. The same idea appears in backup encryption.
2. Set a strong password or passphrase, not just a short PIN, for the laptop sign-in. Memorable passphrases work well for this.
3. Lock the screen automatically after a short idle time, and get in the habit of locking it manually every time you stand up. Most systems have a keyboard shortcut for it.
4. Enable a find-my-device feature if your system offers one, so you can locate, lock or erase it remotely. Test it before you travel. Lost phone tracking works on similar principles.
5. Keep a backup. If the laptop vanishes, your files should not vanish with it. Data backup basics, such as keeping a copy at home or in the cloud, make this a nuisance instead of a disaster. A backup also protects against ordinary failures like spills.
6. Avoid storing passwords in plain files on the laptop. A password manager encrypts them, and many people find it handles this better than notes or spreadsheets.

Handle the network sensibly

Cafe and coworking networks are shared, and the fundamentals are the same as anywhere.

• Confirm the correct network name with staff, since look-alike names exist.
• Treat a network as public when your system asks. This usually turns off file sharing and makes the laptop less visible to others.
• Keep the operating system, browser and apps updated.
• Use two-step sign-in on important accounts.
• Stay alert to browser warnings, and do not install software a network or page tells you to install to get online.
• Save sensitive banking and similar tasks for a trusted connection, or use your phone’s hotspot.

Coworking spaces often offer a more managed network than a cafe, such as individual passwords or separate networks for members. That is helpful, but it still involves other people’s devices, so the same habits apply. If your work is subject to rules about client data, ask your employer or IT team what they require. Workplace security policies often specify things like VPN use and encrypted drives.

Keep your screen to yourself

People nearby can see a surprising amount, including client names, email previews and passwords as you type. A matte privacy screen filter can narrow the viewing angle, which some people find worthwhile. It helps to turn off message previews that pop up on screen when you are in a public place. Good screen privacy habits cost little and are worth building.

Calls, printing and chargers

Sensitive calls are better taken somewhere private, since others can hear. When you need to print, avoid leaving documents in a shared printer. For power, use your own charger in a wall outlet where possible. Public USB ports are a smaller concern for laptops, but a plain wall socket is the simplest option.

If your laptop is lost or stolen

1. Report it to the venue and, where appropriate, to local police, and note any report number.
2. Use find-my-device to lock or erase it, if you set it up.
3. Change passwords for key accounts, starting with email, from another device. The advice on hacked account response applies if you see signs of misuse.
4. Tell your employer promptly if it is a work device or holds work data. Many organizations have a process for exactly this, and acting quickly helps.

Preparing before you leave home does most of the work: encryption, a backup, a strong sign-in and a screen that locks quickly. After that, a laptop in a cafe is a reasonable thing to use, as long as you treat the seat as temporary and the device as something worth keeping an eye on.
