When we connect to a public Wi-Fi network, such as in airports, bars or stations, or a Wi-Fi network without a password, we should not access any website that contains sensitive information, such as banks.

In public Wi-Fi networks or without a password, it would be easy for an advanced user to see all the information that we are sending from our device.

If we want to prevent others from accessing our information on this type of network, we must connect through a VPN service. This type of service consists of a kind of virtual tunnel through which our data will travel encrypted, this way, even if another person reads the content of the WiFi network, they will not be able to see our data.
