Public Wi-Fi networks are everywhere — in coffee shops, airports, hotels, and shopping malls. While these networks are convenient, they can also be dangerous. Hackers often target public Wi-Fi to steal personal data, access bank accounts, or install malware on unsuspecting devices.

So how can you stay safe? Whether you’re checking emails or browsing the web, here are five simple and effective steps to protect yourself from hacking when using public Wi-Fi.
One of the most important rules: never log in to your bank or financial accounts while connected to a public Wi-Fi network. These networks are often unsecured, making it easier for attackers to intercept sensitive information like your login credentials or card details – even by taking screenshots or using other spying techniques.
If you must check your balance or make a transaction, switch to your mobile data instead — it’s much safer.

A Virtual Private Network (VPN) encrypts your internet connection, creating a secure tunnel between your device and the websites you visit. This means even if someone is trying to spy on your traffic, they won’t be able to read or steal your data.
Choose a reliable, well-reviewed VPN — free VPNs may sound appealing but can be risky themselves. A good VPN adds a strong layer of security when you’re connected to any public Wi-Fi.
When you’re in a public place, it’s best to disable features like file sharing, AirDrop, and Bluetooth. These functions can be exploited by hackers nearby to access or send files to your device without your permission.

Most devices allow you to switch to a “Public Network” or “Guest” mode, which automatically turns off these risky settings. Always take a moment to adjust these before connecting.
Whenever you browse the internet, make sure the websites you visit begin with “https://”, not just “http://”. The “s” stands for secure, meaning the connection is encrypted and safer to use.
Many modern browsers also show a padlock icon in the address bar for secure sites. If a site doesn’t have it, avoid entering any personal information.

After using a public Wi-Fi network, it’s a good idea to remove it from your device’s saved networks list. Why? Because your phone or laptop might automatically reconnect to that network in the future — and hackers can exploit this by creating a fake hotspot with the same name.
Taking a few seconds to “forget” the network can prevent unintended connections and keep your device safer in the long run.
Public Wi-Fi can be a lifesaver when you’re on the move — but it comes with risks. By following these five simple steps, you can significantly reduce your chances of being hacked and keep your personal data secure.
