When you use a VPN to browse the internet, you are doing so via an encrypted connection - hence keeping your activity private. If privacy is of a concern to you and you use when you are using Linux, just follow the steps below to secure your connection.
This guide has been written for Ubuntu 18.04, however the steps are likely very similar for different releases and distributions.
|Name||Enter a name that will be used for this connection. I.e. VPN Example Connection|
|Gateway||Enter the server address provided by your VPN provider.|
|Authentication||Select Password, unless you have a key to use, and enter the VPN credentials.|
Now click on the Add button in the top right.
Now all that's left is to use your new VPN connection. Open the System Menu from the right hand side of the top bar and click ok VPN - Connect.
