Tunnelblick is a free, open-source generic VPN app for macOS that allows you to connect to our network via the OpenVPN protocol.

1. Download OpenVPN configuration files

Log into your Proton VPN account at, go to Downloads → OpenVPN configuration files and:

  • Select Platform – The correct platform for your device (this is important, as otherwise you may be vulnerable to DNS leaks)
  • Select Protocol – UDP (recommended) or TCP if you experience slow VPN speeds (this utilizes port 443)
  • Select config file and download – choose whether you want to download a configuration file for a whole country, an individual server, or for a Secure Core server. 
  • Select a country or server and click the Download button next to it. 

You can also scroll to the bottom of the section and select Download all configurations. If you do this, you’ll need a program to extract the resultant zip file.

Drag and drop the configuration files you downloaded into the Configurations section.

The config files use the following naming system:

  • A two-letter abbreviation for the destination country.
  • A number to specify a server in that country. (For example: de-01 is the first server in Germany; ca-04 is the fourth server in Canada.)
  • Files with two country abbreviations are Secure Core servers. (For example: is-us-01 is the Secure Core connection through Iceland to the USA.)

Enter your OpenVPN username and password when prompted. 

Note: This is not your Proton VPN account username or password.

To use our NetShield DNS filtering feature, append the suffix +f1 to your username to block malware, or +f2  to block malware, ads, and trackers (for example 123456789+f2).

Once the configuration is complete, click Connect to connect to Proton VPN.

To add more connections, repeat the steps above with different configuration files for your choice of server or country.
