You've probably heard that public Wi-Fi is dangerous. The truth is more balanced, and knowing the difference helps you focus on what actually matters.
What's less risky than it used to be
Nearly every website and app now encrypts your connection (look for the padlock or https://). That means someone else on the same Wi-Fi generally can't read your passwords or card numbers as they travel. Checking email or browsing at a coffee shop is far safer than it was ten years ago.
What's still worth watching for
- Fake networks. Criminals can set up a hotspot called "Airport Free WiFi" or something close to the hotel's name. Ask staff for the exact network name.
- Login pages that ask for too much. A Wi-Fi sign-in page that wants your email password or card number is a red flag.
- Auto-joining. Turn off "auto-join" for public networks so your phone doesn't connect to look-alikes on its own.
- Out-of-date devices. An unpatched phone or laptop is more exposed on any network. Keep updates on.
Simple habits for the road
- Use your own connection for anything sensitive. Your phone's hotspot works for banking, shopping and anything with a password, and your cellular connection is harder to tamper with than a shared network.
- Consider a reputable VPN if you're on hotel or airport Wi-Fi often.
- Bring your own charger and plug it into a wall outlet. Using public USB charging ports with someone else's cable is a small risk, but a data-blocking adapter is cheap peace of mind. Our Secure Charger USB Kit (3 adapters covering USB-A and USB-C) passes power but blocks data while you charge.
- Keep devices quiet when you're not using them. A signal-blocking Faraday bag blocks cellular, Wi-Fi, Bluetooth and GPS signals, handy for stashing a phone, car key fob or spare device in your bag or hotel room.
