Public Wi-Fi is everywhere—in cafes, airports, malls, and even parks. It’s convenient, especially when you’re working outside or saving on mobile data. But behind that convenience lies a hidden danger. These networks are often unprotected, making it easy for hackers to access your personal data, monitor your online activity, and even steal your identity.
When you connect to public Wi-Fi, you share the same network with strangers. Hackers can position themselves between your device and the internet to intercept your emails, passwords, and files without you even noticing. This method is known as a “man-in-the-middle” attack, and it’s more common than you think.
To stay safe while using public Wi-Fi, avoid accessing sensitive information like online banking, work emails, or cloud storage. If it’s unavoidable, always use a Virtual Private Network (VPN). A VPN encrypts your internet connection, adding a strong layer of protection even if you’re on an open network.
Another good habit is to turn off your device’s auto-connect feature. This prevents your phone or laptop from connecting to random Wi-Fi networks without your permission. Also, make sure websites you visit start with “https” for secure connections and avoid clicking on pop-ups or ads while connected.
Public Wi-Fi is a helpful tool, but it should be used with caution. A few simple safety measures can protect your personal data and give you peace of mind. In a world where online threats are constantly evolving, being cautious with how and where you connect is one of the smartest things you can do.
