It's important to understand that anyone can intercept traffic on public Wi-Fi's. Hackers can easily use tools like packet sniffers to intercept and analyze data being transmitted over a public Wi-Fi network. By doing so, they can collect sensitive information like login credentials, bank account details, and other private data.
To prevent this kind of attack, i think it is essential to use a reputable no-log VPN on any public Wi-Fi network. A VPN creates an encrypted tunnel between your device and the Internet, which makes it impossible for attackers to intercept and view your data. It is the best and most effective method to secure your online identity and keep your data safe while using public Wi-Fi's on the go.
Connecting to another device with a Wi-Fi hotspot can offer some security, but it is not as secure as using a reputable no-log VPN on a free public Wi-Fi network in my opinion. So, if you want to keep your credentials safe and stay secure while on the move and access the internet, always remember to use a reputable no-log VPN on public Wi-Fi networks.
