Why Public Wi-Fi Needs Protection
Public Wi-Fi networks in cafes, hotels, airports, and public transport are incredibly convenient. However, because they are shared by many devices, they present security challenges. Without additional encryption, third parties on the same local network could inspect your DNS lookups or traffic metadata.
What a VPN Does (and Doesn't Do)
A VPN (Virtual Private Network) establishes a secure, encrypted tunnel between your device and the VPN server. * **It does encrypt**: Your network packets, destination IPs, and DNS requests. * **It does not protect**: Against entering your credentials on phishing sites or reusing weak passwords.
Practical Connection Habits
1. Enable your VPN before logging into public portals. 2. Verify you see the secure status in your VPN application. 3. Switch off automatic Wi-Fi connections to prevent joining unverified hotspots.

Is public Wi-Fi safe with HTTPS alone?
HTTPS protects the content of your requests, but local network operators can still see which domains you visit (via DNS lookups). A VPN hides those domains.
