Get started with OpenSSH for Windows

OpenSSH is a connectivity tool for remote sign-in that uses the SSH protocol. It encrypts all traffic between client and server to eliminate eavesdropping, connection hijacking, and other attacks.

An OpenSSH-compatible client can be used to connect to Windows Server and Windows client devices.

Important

If you downloaded the OpenSSH beta from the GitHub repo at PowerShell/Win32-OpenSSH, follow the instructions listed there, not the ones in this article. Some information in the Win32-OpenSSH repository relates to prerelease product that may be substantially modified before it's released. Microsoft makes no warranties, express or implied, with respect to the information provided there.

Prerequisites

Before you start, your computer must meet the following requirements:

  • A device running at least Windows Server 2019 or Windows 10 (build 1809).

  • PowerShell 5.1 or later.

  • An account that is a member of the built-in Administrators group.

Prerequisites check

To validate your environment, open an elevated PowerShell session and do the following:

  • Enter winver.exe and press enter to see the version details for your Windows device.

  • Run $PSVersionTable.PSVersion. Verify your major version is at least 5, and your minor version at least 1. Learn more about installing PowerShell on Windows.

  • Run the following command. The output shows True when you're a member of the built-in Administrators group.

    (New-Object Security.Principal.WindowsPrincipal([Security.Principal.WindowsIdentity]::GetCurrent())).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

To enable SSHD using Server Manager:

  1. In Server Manager, on the navigation pane to the left, select Local Server.

  2. In the Properties window, locate Remote SSH Access.

  3. Select Disabled to enable the OpenSSH service.

Note

If you need to allow or restrict specific users or groups from using OpenSSH for remote access, add them to the OpenSSH Users user group.

Note

Installing OpenSSH Server will create and enable a firewall rule named OpenSSH-Server-In-TCP. This allows inbound SSH traffic on port 22. If this rule is not enabled and this port is not open, connections will be refused or reset.

Connect to OpenSSH Server

Once installed, you can connect to OpenSSH Server from a Windows or Windows Server device with the OpenSSH client installed. From a PowerShell prompt, run the following command.

ssh domain\username@servername

Once connected, you get a message similar to the following output.

The authenticity of host 'servername (10.00.00.001)' can't be established.
ECDSA key fingerprint is SHA256:(<a large string>).
Are you sure you want to continue connecting (yes/no)?

Entering yes adds that server to the list of known SSH hosts on your Windows client.

At this point, the service prompts you for your password. As a security precaution, the characters of your password aren't displayed as you enter them.

Once connected, you should see the following Windows command shell prompt:

domain\username@SERVERNAME C:\Users\username>
