Quick answerPublic Wi-Fi is reasonably safe for browsing HTTPS websites and apps, because that traffic is encrypted. The real risks are fake hotspots with names like the venue's, login pages that ask for personal or card details, and devices with sharing turned on. Confirm the network name with staff, avoid entering sensitive details on captive portals, keep your device updated, and use mobile data for banking if unsure.
A decade ago, public Wi-Fi was genuinely dangerous because many sites didn't use encryption. Today almost every website and app uses HTTPS, so someone on the same network can see which sites you visit but not what you type. That doesn't mean there's no risk.
What's still risky
- Evil twin hotspots: a fake network named "Airport_Free_WiFi" set up by an attacker.
- Captive portals asking for your email password, CNIC or card details to "get online".
- File sharing, AirDrop or network discovery left on, exposing your device to others nearby.
- Old, unpatched phones and laptops.
Five habits
- Ask staff for the exact network name.
- Never enter passwords or card details on a Wi-Fi sign-in page.
- Turn off file sharing and set the network as "Public" on Windows.
- Keep your device and browser updated.
- Use mobile data for banking and payments if you're unsure about the network.
Frequently asked questions
Do I need a VPN on public Wi-Fi?
For most people browsing HTTPS sites, a VPN isn't essential, but a reputable one adds protection on untrusted networks and hides which sites you visit from the network owner.
Can someone hack my phone through public Wi-Fi?
It's rare on an updated phone. The more common risks are fake login pages and fake hotspots that trick you into entering details.
