Story summary
- Travelers should enable VPN auto-connect and kill-switch settings before using public Wi-Fi networks.
- A kill switch blocks all traffic when the VPN drops, keeping the device’s IP hidden.
- Captive portals at airports or hotels require sign-in before the VPN can connect.
- Users should select a fast-reconnecting VPN protocol to stay protected while moving between Wi-Fi and cellular.
- Most sites use HTTPS, so brief VPN loss only exposes unencrypted traffic.
