Note: We have an official ProtonVPN app for Windows that provides the easiest way to connect to our servers and allows you to benefit from many of ProtonVPN’s advanced features. For example:
- Kill switch and permanent kill switch
- Choose between IKEv2, OpenVPN, and WireGuard VPN protocols
- Smart protocol
- DNS leak protection
- NetShield Ad-blocker
- Moderate NAT
- VPN Accelerator
- Port forwarding
You can also connect to ProtonVPN servers manually using the following VPN protocols:
- OpenVPN (using OpenVPN GUI )
- WireGuard (using any “vanilla” WireGuard client, including the official open-source app)
- IKEv2 (using the built-in Windows VPN client)
In this guide, we show you how to manually configure devices running Windows 10 to connect to our servers using the IKEv2 protocol. The instructions for Windows 11 are very similar.
Please note that connecting in this way means you will not benefit from the advanced features available through the official ProtonVPN Windows app.
