How to Securely SSH to a Windows Server: A Guide for Devs

As a developer, you may need to access a Windows server for various reasons such as deploying new applications or debugging existing ones. One of the most secure and reliable ways to do this is through Secure Shell (SSH). In this article, we will guide you through everything you need to know about SSH to a Windows server.

What is SSH?

Secure Shell or SSH is a network protocol that allows secure communication between two computers. It is commonly used for remote login, file transfers, and executing commands on a remote server. SSH provides encryption of data exchanged during the communication, which ensures security and privacy.

How does SSH work?

SSH works by establishing a secure connection between two computers using cryptographic keys. When a user tries to connect to a remote server, the SSH client requests the server’s public key. The client then verifies the key’s authenticity, and if it is valid, the client sends its public key to the server. The server then uses the client’s public key to encipher a session key that will be used for the rest of the session. This ensures that all data exchanged during the session is encrypted and secure.

Why use SSH?

SSH is widely used for its security features. It provides encryption of data exchanged between two computers, making it difficult for attackers to intercept and read the information. Therefore, SSH is commonly used for remote login and file transfers, as it ensures that any sensitive information is kept secure. In addition, SSH provides a simple and efficient way to manage remote servers.

How is SSH different from Telnet?

Telnet is an older and less secure protocol that provides the same functionality as SSH. However, Telnet does not provide encryption of data exchanged during the communication, which makes it less secure. SSH, on the other hand, provides encryption of data, making it a more secure protocol than Telnet.

How to SSH to a Windows Server

Step 1: Install OpenSSH

The first step to SSH to a Windows server is to install OpenSSH. OpenSSH is an open-source implementation of the SSH protocol that is available for Windows. You can install OpenSSH using PowerShell, which comes pre-installed on Windows 10.

Get-WindowsCapability -Online -Name OpenSSH.Client*
Check if OpenSSH is installed on your computer.
Add-WindowsCapability -Online -Name OpenSSH.Client*
Install OpenSSH on your computer.

Step 2: Connect to the Windows Server

Once OpenSSH is installed on your computer, you can establish a connection to the Windows server using SSH. To connect to a remote server, you need to know the server’s IP address, username, and password.

Step 3: Configure Firewall

If you are connecting to a Windows server that has a firewall enabled, you need to configure the firewall to allow SSH connections. You can open the required ports on the firewall using PowerShell.

Step 4: SSH into the server

Once you have installed OpenSSH, connected to the server, and configured the firewall, you can SSH into the Windows server using your command prompt or terminal.

ssh username@ip_address
Connect to the Windows server using SSH.


What if I forget my SSH password?

If you forget your SSH password, you can reset it by following these steps:

  1. Log in to the server using an alternative method such as RDP.
  2. Open PowerShell as an administrator.
  3. Run the following command: `net user username new_password`

How can I improve SSH security?

Here are some tips to improve SSH security:

  • Use strong passwords or SSH keys.
  • Disable root login.
  • Use a non-standard port for SSH.
  • Install updates regularly to fix security vulnerabilities.

What port does SSH use?

By default, SSH uses port 22. However, you can configure SSH to use a different port for security reasons.


SSH is a secure and reliable way to access a Windows server remotely. With OpenSSH installed on your Windows computer, you can establish a secure connection to a remote server and execute commands safely. By following the steps outlined in this guide, you can set up an SSH connection to a Windows server quickly and easily.
