Picture this — you're at a cafe, you open your banking app on the free WiFi. Feels convenient. But what if the person at the next table could read your password?
Public (open) WiFi is easy because it needs no password to join — but that very "openness" is what makes it risky.
The dangers on public WiFi
- Packet sniffing — tools exist that capture and read the data flowing across a network. If it isn't encrypted, your passwords and messages can be exposed.
- Evil Twin (fake hotspot) — an attacker sets up a look-alike hotspot named "Free_Cafe_WiFi"; if you connect, all your traffic passes through them.
- Session hijacking — stealing the session of an account you're logged into, letting them get into your account.
- Malware spreading — some open networks are used to push malware onto devices.
How a VPN protects you
A VPN encrypts everything leaving your device and sends it through a secure tunnel. So —
- Even if someone captures the data, it's encrypted and unreadable (just gibberish).
- Even if you connect to a fake hotspot, they can't see what's inside the tunnel.
- Your passwords, messages and banking data stay safe.
Tips for staying safe on public WiFi
- Keep your VPN on — especially for banking, email and important accounts.
- Confirm the network name with staff once (to avoid fake hotspots).
- Turn off "auto-connect to open networks."
- Don't enter sensitive data on sites without HTTPS (🔒).
