Free Wi-Fi networks are available everywhere, including restaurants, hotels, colleges, and airports. This allows anyone and everyone to check their emails or social media. But to get access to these networks, authentication (username and password) are necessary. Yet transmitting such important information over the public Wi-Fi can be risky given its accessibility to anyone. When you’re using such an insecure Wi-Fi network, it’s a good idea to use a VPN so your traffic is encrypted, meaning that even if it is intercepted, your data will be scrambled.
