📎How to install a VPN? (On a VPS)

For a VPN, you can use different software. In this tutorial, we will install WireGuard and OpenVPN!

What is a VPN?

A VPN is a secure tunnel on the Internet that encrypts your Internet traffic and protects your online privacy. It ensures that no one else can see what you are doing on the Internet and where you are. For example, you can safely use public Wi-Fi networks and bypass geographical restrictions to access content that would otherwise be unavailable. It also makes your own IP address unavailable.

A VPN encrypts your data, that way hackers can't see it!

What is the difference between WireGuard and OpenVPN?

WireGuard is faster, more secure and easier to configure than OpenVPN, but has less support because it is a relatively new technology. WireGuard and OpenVPN are both secure for setting up VPN connections. But because WireGuard uses newer cryptographic technologies, it is generally considered more secure.

Go to the WireGuard installation.

Go to the OpenVPN installation.
