Oct 13, 2025 by wbrum.org 141 views

Introduction

Windows 11 has made significant strides in providing a seamless user experience, but it still lacks the flexibility of Linux-based systems when it comes to remote access. SSH (Secure Shell) is a powerful tool that allows users to securely access and manage remote systems. However, Windows 11's built-in SSH client is limited, and users are often forced to rely on third-party solutions. In this article, we will explore the possibility of SSHing into Windows 11 as a user without a password.

Understanding Windows 11's SSH Client

Windows 11's built-in SSH client is based on OpenSSH, a popular open-source implementation of the SSH protocol. While it provides a basic level of functionality, it lacks some of the advanced features found in other SSH clients. One of the main limitations of Windows 11's SSH client is its inability to connect to a remote system without a password.

Using Plink to SSH into Windows 11

Plink is a command-line SSH client that comes bundled with the OpenSSH package on Windows 11. It allows users to connect to a remote system using SSH, but it requires a password to authenticate. However, there is a workaround that allows users to SSH into Windows 11 without a password.

To use Plink to SSH into Windows 11 without a password, you will need to create a new user account on your Windows 11 system. This account should have no password, as you will be using a public key to authenticate. Here's how to do it:

Step 1: Create a new user account

Open the Start menu and click on the "Settings" icon.
Click on "Accounts" and then click on "Family & other users."
Click on "Add someone else to this PC" and follow the prompts to create a new user account.
Make sure to select the option to create a new user account without a password.

Step 2: Generate a public key

Open a command prompt as an administrator.
Type the following command to generate a public key: ssh-keygen -t rsa -b 2048
Follow the prompts to save the public key to a file.

Step 3: Copy the public key to the remote system

Open a command prompt as the new user account you created.
Type the following command to copy the public key to the remote system: plink -P 22 user@remote-system "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys" < public-key-file
Replace "user" with the username of the account you created, "remote-system" with the hostname or IP address of the remote system, and "public-key-file" with the path to the public key file.

Step 4: SSH into the remote system

Open a command prompt as the new user account you created.
Type the following command to SSH into the remote system: plink -P 22 user@remote-system
You should now be logged in to the remote system without a password.

Using PuTTY to SSH into Windows 11

PuTTY is a popular SSH client for Windows that provides a graphical interface for connecting to remote systems. While it is not as powerful as some other SSH clients, it is easy to use and provides a high level of flexibility.

To use PuTTY to SSH into Windows 11 without a password, you will need to create a new user account on your Windows 11 system, as described above. You will also need to generate a public key and copy it to the remote system, as described above.

Here's how to use PuTTY to SSH into Windows 11 without a password:

Step 1: Launch PuTTY

Open PuTTY and click on the "Session" icon.
Enter the hostname or IP address of the remote system in the "Host Name" field.
Select the "SSH" protocol from the "Protocol" dropdown menu.
Click on the "Save" button to save the session.

Step 2: Configure the session

Click on the "Connection" icon.
Select the "Auth" tab.
Click on the "Browse" button to select the public key file.
Click on the "Save" button to save the changes.

Step 3: SSH into the remote system

Click on the "Open" button to connect to the remote system.
You should now be logged in to the remote system without a password.

Conclusion

SSHing into Windows 11 as a user without a password is possible using Plink and PuTTY. By creating a new user account without a password and generating a public key, you can use these tools to connect to the remote system without entering a password. While this method may not be as secure as using a password, it provides a convenient way to access remote systems without the need for a password.

Troubleshooting

If you encounter any issues while trying to SSH into Windows 11 without a password, here are some common troubleshooting steps to try:

Make sure that the public key is correctly generated and copied to the remote system.
Check that the user account you created has no password.
Verify that the SSH client is correctly configured to use the public key for authentication.
Try using a different SSH client, such as PuTTY, to see if the issue is specific to Plink.
