How to Fix Bad Owner or Permissions Error on SSH Config in Windows 11

When using SSH on Windows 11, you might encounter a “bad owner or permissions” error related to your SSH configuration files. This error usually happens because the SSH client expects strict file permissions for security reasons. If these permissions are not set correctly, SSH will refuse to use the configuration or key files.

Fixing this error is important to ensure you can connect to remote servers securely without interruptions. Fortunately, the solution involves adjusting file ownership and permissions in a few straightforward steps. This guide will walk you through each step in a simple and clear way.

Whether you are new to SSH or just need a quick fix, following these instructions carefully will help you resolve the issue on Windows 11 quickly. Let’s get started with some quick checks before diving into the detailed steps.

By the end of this article, you’ll understand why permissions matter and how to set them correctly to avoid this common SSH error.

Quick Note: Prerequisites and Checks

Before making any changes, ensure the following:

  • You have administrative access to your Windows 11 system or permission to change file properties.
  • Your SSH client is the built-in Windows OpenSSH or another compatible SSH program.
  • You know the location of your SSH configuration files, usually in C:UsersYourUsername.ssh.
  • You understand that improper permissions can expose sensitive files, so be careful when changing them.

Step 1: Locate Your SSH Folder and Files

The first step is to find the folder where your SSH keys and config files are stored. By default, this is in your user profile directory under .ssh. For example:

C:UsersYourUsername.ssh

Open File Explorer and navigate to this folder. You should see files like id_rsa (your private key), id_rsa.pub (your public key), and possibly a config file.

Knowing the exact location is important because the permissions need to be set on these specific files and folder.

Step 2: Understand Why Permissions Matter

SSH requires that your private key files and configuration files are only accessible by you, the owner. If these files are readable or writable by other users, SSH will refuse to use them for security reasons. This is why you get the “bad owner or permissions” error.

On Windows, file permissions work differently than on Linux, but the goal is the same: make sure your SSH files are private to your user account.

Step 3: Change Ownership of SSH Files

Sometimes the ownership of the files might not be assigned to your user account. To fix this:

  1. Right-click the .ssh folder and select Properties.
  2. Go to the Security tab.
  3. Click Advanced.
  4. At the top, check the Owner. If it’s not your username, click Change.
  5. Type your Windows username and click Check Names to verify.
  6. Click OK to set the ownership.
  7. Make sure to check “Replace owner on subcontainers and objects” to apply changes to all files inside.
  8. Click Apply and then OK to close.

Changing ownership ensures that your user account fully controls the SSH files, which is necessary for proper permissions.

Step 4: Adjust File Permissions to Be Restrictive

Next, you need to restrict file permissions so only your user account has access:

  1. Right-click the .ssh folder, go to Properties, then the Security tab.
  2. Click Edit to change permissions.
  3. Remove any users or groups except your own user account and SYSTEM (if present).
  4. For your user account, make sure Full control is checked.
  5. Click Apply and then OK.
  6. Repeat this process for each key file (e.g., id_rsa) inside the folder.

This step prevents other users from reading your keys, which SSH enforces for security.

Step 5: Use PowerShell to Set Permissions (Alternative Method)

If you prefer using a command line, PowerShell can help set permissions precisely:

  1. Open PowerShell as Administrator.
  2. Run the following command to reset permissions on your .ssh folder:
icacls $env:USERPROFILE.ssh /inheritance:r /grant:r "$($env:USERNAME):(F)" /t

This command removes inherited permissions and grants full control to your user recursively.

Using PowerShell is faster and ensures consistent permissions across all files.

Step 6: Verify Permissions and Test SSH

After changing ownership and permissions, test your SSH connection again:

  • Open Command Prompt or PowerShell.
  • Try connecting to your SSH server, for example:
ssh user@hostname

If the “bad owner or permissions” error no longer appears, the issue is fixed.

If you still see the error, double-check the permissions or try restarting your computer and testing again.

Frequently Asked Questions (FAQs)

Why does SSH care so much about file permissions?

SSH uses private keys to authenticate securely. If these keys are accessible by others, it can lead to security risks. Strict permissions ensure only the rightful user can access these sensitive files.

Can I use other SSH clients on Windows 11?

Yes, but permissions must still be set correctly. Some clients might not enforce strict permissions as the built-in OpenSSH does, but it’s best practice to keep keys secure regardless.

What if my SSH folder is missing?

You can create it manually in your user profile directory as .ssh. Then place or generate your SSH keys inside.

Is it safe to give Full Control permission to my user account?

Yes, because the files should only be accessible by your user account. Avoid giving permissions to other users or groups.

Can I fix permissions using Windows Subsystem for Linux (WSL)?

Yes, you can use Linux commands inside WSL to adjust permissions, but remember that Windows and WSL handle permissions differently. It is generally easier to fix permissions directly in Windows for SSH running in Windows.

When Nothing Works

If you continue to face issues after following all steps, consider these final options:

  • Check official Microsoft documentation for Windows OpenSSH: Microsoft OpenSSH Docs.
  • Delete your current SSH keys and generate new ones with ssh-keygen to avoid corrupted files.
  • Reset permissions on your entire user profile if you suspect broader permission problems.
  • Use third-party SSH clients like PuTTY as an alternative, which do not rely on strict Windows permissions.

If needed, seek help on forums such as Stack Overflow or Microsoft Tech Community where many users share solutions for SSH issues on Windows.

Conclusion

“Bad owner or permissions” errors in SSH on Windows 11 are common but straightforward to fix. The root cause is usually improper file ownership or overly permissive access on your SSH files. By locating your SSH folder, ensuring your user account owns the files, and setting restrictive permissions, you can resolve this error quickly.

Using either the graphical interface or PowerShell commands, you can control file permissions securely. Always remember that SSH enforces strict rules to protect your private keys and keep your connections safe.

Following these simple steps will help you maintain a secure SSH setup and avoid frustrating connection errors in the future.
