What is a VPN?
A virtual private network (VPN) gives you online privacy and anonymity by creating a private network from a public internet connection. Most importantly, VPN services establish secure and encrypted connections to provide greater privacy than even a secured Wi-Fi hotspot.
Where do you need to use?
Most people won't need to log into a VPN service when accessing the internet from home.
Nor when accessing the internet from an Android smartphone or iPhone.
But when you need to use public wifi or any internet that you are not 100% confident in, then it’s helpful to use a VPN. Or if you need to signal that you are located in a different country to be able to access services that limit access by country you need a VPN.
