Free VPN for Kali Linux: Proton VPN Setup + whoami Anonymity Tool

Quick answer: The easiest free VPN for Kali Linux is Proton VPN’s free plan, which has no data limit and supports OpenVPN and WireGuard. Download a free config file from your Proton account, then connect with sudo openvpn yourfile.ovpn or sudo wg-quick up ./yourfile.conf. For extra anonymity, the whoami tool can route traffic through Tor. Tor is not a VPN, though.

Introduction Free VPN for Kali Linux

Welcome to Cyber Weapons Lab – Episode 01 Free VPN for Kali Linux!
If you’re using Kali Linux for ethical hacking or penetration testing, securing your connection is a top priority. In this episode, we’ll guide you step-by-step on how to set up a completely free VPN on Kali Linux, helping you stay anonymous and protect your privacy online.

Whether you’re a cybersecurity student, a bug bounty hunter, or a professional penetration tester, this guide is essential for creating a safer hacking environment.

VPN vs Tor vs whoami

Method 1: Proton VPN with OpenVPN

1. Create a free account at protonvpn.com.
2. Go to Account → OpenVPN/IKEv2 username and copy your OpenVPN credentials.
3. Go to Downloads → OpenVPN configuration files, choose Linux, UDP and a free server, then download the .ovpn file.
4. In Kali, run:

sudo apt update && sudo apt install openvpn -y
sudo openvpn ~/Downloads/your-free-server.ovpn

5. Enter the OpenVPN username and password from step 2. When you see “Initialization Sequence Completed”, you’re connected.

Method 2: WireGuard (faster)

1. In your Proton account, go to Downloads → WireGuard configuration, pick a free server and download the .conf file.
2. Run:

sudo apt install wireguard resolvconf -y
sudo wg-quick up ~/Downloads/proton-free.conf
# to disconnect:
sudo wg-quick down ~/Downloads/proton-free.conf

Method 3: whoami (your current content, corrected)

sudo apt update && sudo apt install tar tor curl python3 python3-scapy network-manager -y
git clone https://github.com/owerdogan/whoami-project.git
cd whoami-project && sudo make install
sudo kali-whoami --start    # enable
sudo kali-whoami --stop     # disable

whoami routes your traffic through Tor and changes system identifiers. It gives you anonymity, but it’s slower than a VPN and isn’t a VPN.

Check the exact install and start commands against the project’s README, because they can change between versions.

How to check it’s working

1. Before connecting, note your IP at whatismyipaddress.com (with the correct spelling).
2. Connect, then check again. The IP and country should change.
3. Run a DNS leak test at dnsleaktest.com. Only your VPN provider’s servers should appear.

Troubleshooting

• “AUTH_FAILED”: use your OpenVPN username and password from the Proton account page, not your Proton login.
• No internet after connecting: run sudo systemctl restart NetworkManager and reconnect.
• Using TryHackMe or Hack The Box? Disconnect from the free VPN first. Running two VPNs at once usually breaks routing.

Conclusion

A free VPN on Kali Linux takes about five minutes with Proton VPN, using OpenVPN or the faster WireGuard. Add the whoami tool when you want Tor-level anonymity, and always run a leak test before you trust the connection. Remember: anonymity tools are for privacy and authorised testing only.
