The last rush of summer travel is here, and so is the ritual that comes with it: land at the gate, phone at one percent, and lunge for the nearest “Free Airport WiFi” network before you’ve even found your luggage carousel. Hotels are no better. You check in, the WiFi password is printed on a card at the front desk, and you connect without a second thought because you just want to text someone that you landed.
None of that is unusual, and none of it makes you careless. But public networks at airports, hotels, and cafes work differently from your network at home, and it’s worth a few minutes before your next trip to get the habits right.
Why public networks deserve a little more caution
At home, you control the router, the encryption, and who else is on the network. On a public network, you’re sharing space with hundreds of strangers, and you have no way to know how well it’s secured or who set it up. Some airport and hotel networks are run well. Others are outdated, unencrypted, or loosely monitored. You usually can’t tell which is which just by looking at the login screen.
The bigger risk isn’t always the network itself, it’s what a bad actor can do by sitting on the same network as you. That can include creating a lookalike hotspot with a name like “Airport_Free_WiFi_2” to trick you into connecting to their equipment instead of the real thing, then watching what passes through. It’s a similar trick to how fake charity scams spike during disaster season: the setup preys on people who are distracted, in a hurry, or trying to do something helpful or ordinary. Travel puts you in exactly that state of mind.
None of this means public WiFi is a trap you should avoid entirely. It means a few precautions go a long way.
Before you leave home
Update your devices. Security patches close known holes, and an outdated phone or laptop is an easier target. Do this before you travel, not while you’re standing at a gate on airport WiFi.
Turn off auto-join for open networks. Most phones will automatically reconnect to networks they’ve used before, and some will offer to join any open network nearby. Turn that off in your WiFi settings so you’re choosing each connection deliberately.
Consider a VPN if you’ll be handling anything sensitive. A VPN encrypts your traffic so that even on a questionable network, what you send is much harder to intercept. It’s not a requirement for checking a weather app, but if you’ll be logging into a bank or work account while traveling, it’s worth setting up in advance.
Check your passwords are actually strong. If it’s been a while, this is a decent moment to also handle any accounts you’ve been putting off, the same way you might tackle resetting school portal passwords for the new year once summer ends. Fresh passwords before a trip mean one less thing to worry about while you’re away.
Connecting at the airport or hotel
Ask staff for the exact network name. Don’t just pick the most convenient-looking option from the list. Fake hotspots often use names that look almost identical to the real one. A quick question at the desk or gate confirms you’re joining the right network, not an imitation sitting a few feet away.
Avoid networks that ask for more than a password. A legitimate hotel or airport network might ask for a room number or a simple login. Be wary of any public WiFi login page that asks for a credit card number, your full name and address, or other personal details beyond what’s needed to connect.
Skip sensitive logins on public WiFi when you can. Checking a flight status or browsing the news is low-risk. Logging into your bank, entering a credit card number, or accessing work systems is a bigger ask of a network you don’t control. If it can wait until you’re on a trusted connection, let it wait. If it can’t, use a VPN and make sure the site itself uses “https” before entering anything sensitive, the same instinct covered in credit card security online.
Turn off file sharing and AirDrop-style features. These are convenient at home and unnecessary risk on a network full of strangers. Most phones let you switch sharing to “off” or “contacts only” in a few taps.
Watch for the padlock, but don’t rely on it alone. A padlock icon and “https” mean your connection to that specific site is encrypted, which is good, but it doesn’t mean the WiFi network itself is safe or that the site is legitimate. Treat it as one signal among several, not a guarantee.
Traveling with kids and their devices
Travel days are exactly when kids end up handed a tablet or phone to keep them occupied, often connected to whatever WiFi is available without much thought. A few extra minutes of setup helps:
- Make sure any parental controls or content restrictions are already in place before you leave, not something you’re fumbling with at the gate. If your household set these up on a console or device recently, the same family sharing and content restriction principles apply to phones and tablets on the road.
- If your child wears a GPS smartwatch or has location sharing turned on with friends, a hotel or unfamiliar city is a good moment to revisit that conversation. Talking to teens about sharing location with friends matters more, not less, when everyone’s routine is disrupted by travel.
- If your child is starting school right after the trip and you’re weighing a smartwatch built for a kid heading back to class, check what data it collects and where it sends it, the same scrutiny worth applying to any school app collecting information about your child.
A short checklist for the trip
- Update devices before departure
- Turn off auto-join for open networks
- Confirm the exact network name with staff
- Use a VPN for anything sensitive
- Avoid banking or major purchases on public WiFi when possible
- Turn off file sharing and similar features while traveling
- Double check kids’ devices and location settings before you go
The habit that matters most
None of these steps require technical skill, and none of them will slow down your trip in any meaningful way. The one habit worth keeping above all the others is simple: pause before you connect. Confirm the network, ask if you’re not sure, and treat sensitive logins as something that can wait for a connection you trust. That small pause is doing more work than any single setting or app ever could.
A quick safety note
This article is general information, not professional security, legal, or medical advice. No single tool or setting makes anyone completely safe; security works in layers. If you are dealing with a live incident, such as active fraud, ransomware, or a child in danger, contact the appropriate professionals or authorities.
