🔐 How to Configure SSH Access to pfSense Firewall Using Public Key Infrastructure (PKI) | Full Secure Setup Guide
Welcome to this in-depth tutorial where we walk you through how to set up SSH access to your pfSense firewall using Public Key Authentication (PKI) — one of the most secure ways to manage remote access on your network.
Whether you're managing a home lab, a small business network, or an enterprise environment, this guide will help you implement strong authentication mechanisms and reduce your reliance on passwords.
💡 In this video, you will learn how to:
✔️ Enable and configure the SSH server on pfSense
✔️ Generate a secure SSH key pair on your local machine (Linux, macOS, or Windows with PuTTY or OpenSSH)
✔️ Upload and configure your public key in pfSense
✔️ Restrict SSH access using firewall rules and best practices
✔️ Test and verify the SSH login using your private key
✔️ Disable password-based login to enforce public key authentication only
🚀 Why This Is Important:
Using public key authentication instead of passwords significantly strengthens your security. Passwords can be guessed or brute-forced — public keys cannot. This setup is especially vital when managing your firewall remotely over an unsecured network.
🔒 Key Benefits of SSH with PKI on pfSense:
No more password authentication — safer and faster logins
Reduced risk of brute-force attacks
Easy to manage multiple keys for multiple users
Fully compatible with common SSH clients like PuTTY, OpenSSH, and Termius
Works seamlessly with pfSense 2.7.x and 2.8.x
