Use a VPN on Public WiFi for Security

The Problem

You connect to Starbucks WiFi and check your bank account. Anyone on the same network could intercept your data.

The Hack

Install a VPN app (ProtonVPN free, or NordVPN/ExpressVPN paid). Turn it on before connecting to any public WiFi.

Why It Works

Public WiFi transmits data unencrypted. A VPN creates an encrypted tunnel between your device and the internet, making your data unreadable to anyone on the same network.

Pro Tips

• ProtonVPN has a usable free tier
• NordVPN and ExpressVPN are $3-5/month and faster
• Turn VPN on automatically when joining unknown WiFi networks
• Never access banking or sensitive accounts on public WiFi without VPN
