SSH Client for Windows – PuTTY and Alternatives

Windows offers several SSH client options in 2026. PuTTY remains the most widely used standalone SSH client for Windows, but the built-in OpenSSH shipped with Windows 10 and 11, WinSCP, and MobaXterm all serve specific workflows. This guide compares each tool so you can choose the right ssh client windows setup for your environment.

Quick Comparison

PuTTY

PuTTY is the most widely deployed SSH client for Windows in enterprise environments. It has been continuously maintained since 1999 and supports SSH, Telnet, rlogin, and serial connections. The full suite includes auxiliary tools: PuTTYgen (key generation), Pageant (key agent), Plink (CLI automation), PSCP (SCP file transfer), and PSFTP (interactive SFTP).

PuTTY Strengths

• Mature, well-tested codebase with active security patches.
• Stores multiple named session profiles with custom colours, fonts, and connection settings.
• Supports serial connections — useful for routers, switches, and embedded devices.
• Portable — single .exe with no installation required.
• Deep configuration options for terminal emulation.

PuTTY Limitations

• GUI only — no native tab support (use SuperPuTTY or Windows Terminal wrapper for tabs).
• Uses the PPK key format by default (though it can read OpenSSH keys via PuTTYgen conversion).
• Older interface compared to modern alternatives.

Windows Built-In OpenSSH Client

Since Windows 10 version 1809 (October 2018), an OpenSSH client is available as an optional feature. It provides the standard ssh, scp, sftp, and ssh-keygen commands in PowerShell and Command Prompt.

# Check if OpenSSH client is installed
Get-WindowsCapability -Online | Where-Object Name -like "OpenSSH.Client*"

# Install if not present (requires admin)
Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

# Basic connection (same syntax as Linux/macOS)
ssh user@example.com

# Connect with a specific key
ssh -i C:Usersyou.sshid_ed25519 user@example.com

OpenSSH Strengths on Windows

• Standard ~/.ssh/ directory and authorized_keys workflow — identical to Linux.
• Native PowerShell integration — no separate tool needed.
• Works with ssh-agent service for key caching (Windows equivalent of Pageant).
• Scriptable via PowerShell or batch files using familiar Unix-style options.

Enabling the Windows ssh-agent Service

The built-in Windows SSH agent service functions similarly to Pageant for OpenSSH keys:

# Enable and start the SSH Agent service (requires admin)
Set-Service -Name ssh-agent -StartupType Automatic
Start-Service ssh-agent

# Add your key to the agent
ssh-add C:Usersyou.sshid_ed25519

# Verify loaded keys
ssh-add -l

WinSCP

WinSCP is a free graphical file transfer client for Windows that supports SFTP, SCP, FTP, and WebDAV. It integrates with PuTTY sessions and can import PuTTY session profiles, making it a popular companion tool. WinSCP also includes a scripting engine for automated transfers.
