How to Remotely Access Linux from Windows 10 (Fast & Secure SSH Setup)

The Goal

To establish a secure remote connection from a Windows 10 workstation to a Linux server using SSH (Secure Shell)—without entering a password every time.

The Lab

We’ll use the following setup:

• Workstation: Windows 10.
• Remote server: Linux VM with IP 10.0.10.101 on the 10.0.10.0/24 network.
• Tools: Built-in Windows SSH client, PowerShell, Linux command line.

The Why

SSH is the preferred method for securely connecting to remote servers. It encrypts all communication and supports key-based authentication. Passwordless logins not only make repeated access more convenient—they’re also more secure and automation-friendly.

The How

1. Install the SSH Client on Windows 10

• Go to Settings > Apps > Optional features
• Click Add a feature, search for "OpenSSH Client"
• Install it and close the Settings window

2. Test SSH Access with Password

Open PowerShell and connect to the server:

ssh username@10.0.10.101

• Accept the fingerprint when prompted (yes)
• Enter your password and verify the login works

3. Generate an SSH Key Pair

In PowerShell:

ssh-keygen

• Accept the default path (e.g. C:\Users\<your-username>\.ssh\)
• Leave the passphrase empty for convenience
• Keys are now stored as:
  • id_rsa (private key)
  • id_rsa.pub (public key)

4. Confirm the Keys Exist

cd $env:USERPROFILE\.ssh
ls

Ensure you see both id_rsa and id_rsa.pub.

5. Copy the Public Key to the Linux Server

From PowerShell, run:

type $env:USERPROFILE\.ssh\id_rsa.pub | ssh username@10.0.10.101 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

This sends your public key to the Linux server and appends it to the authorized_keys file.

The Results

Once the public key is added:

ssh username@10.0.10.101

You’ll connect without being prompted for a password. This confirms your Linux server recognizes and trusts the private key stored locally.

The Conclusion

Passwordless SSH access from Windows to Linux is simple, secure, and ideal for developers, administrators, or anyone managing multiple remote systems. Once configured, remote tasks become more efficient—and less error-prone.
