Public WiFi safety checklist
- Verify the network name with staff—fake “Free Airport WiFi” hotspots are common
- Enable your VPN before connecting (we recommend ExpressVPN for one-click protection)
- Disable file sharing in system settings to block local network access
- Stick to HTTPS sites (look for 🔒 in your browser bar)
- Avoid sensitive logins like banking unless absolutely necessary
- Use a privacy browser like Firefox or Brave for extra tracking protection
- Turn off auto-connect to WiFi in your device settings
For high-risk situations (journalists, activists), consider advanced privacy tools beyond basic VPN protection.
Public WiFi safety FAQs
Can hotels see what I do on their WiFi?
Yes—hotel networks often log traffic. A VPN like NordVPN encrypts your activity so they only see scrambled data.
Are airport WiFi networks safe?
No. Crowded hubs are prime targets for “evil twin” attacks where hackers mimic legitimate networks. Always use a VPN and verify the exact network name.
Do free VPNs protect me?
Most free VPNs lack proper encryption or sell your data. Proton VPN's free tier is the only exception we trust for basic protection.
How can I tell if a VPN is working?
Visit IPLeak.net—if it shows your VPN's IP location (not your real one) and no DNS leaks, you're protected.
Stay safe on any network
Public WiFi threats evolve, but a reliable VPN is your first line of defense. ExpressVPN offers 24/7 support if you need help setting up protection at cafes, hotels, or transit hubs.
