VSCode Still Asking for Password After SSH Key Setup? Here's the Fix!

Scenario: You've meticulously set up your SSH key to streamline remote server connections, but VSCode keeps stubbornly prompting for your password. Frustrating, right? Let's troubleshoot this common issue and get you connected smoothly.

The Problem: Even with a valid SSH key, VSCode might still ask for your password for a few reasons.

• Incorrect permissions: Your SSH key needs specific permissions to work correctly.
• Missing configuration: VSCode might not be properly configured to use your SSH key.
• SSH agent issues: The SSH agent, which stores your SSH keys for easy access, might be malfunctioning or improperly configured.

Original Code (Example):

# Setting up SSH keys (using ssh-keygen):
ssh-keygen -t ed25519 -C "[email protected]"

# Adding your public key to the remote server:
ssh-copy-id -i ~/.ssh/id_ed25519 user@remote_server_ip

Analyzing the Issue:

1. Permissions Check: The file containing your private SSH key (usually ~/.ssh/id_ed25519 or ~/.ssh/id_rsa) must have strict permissions. The owner should have read and write access, while everyone else should have no access. Use the following command to check and adjust permissions:

   chmod 600 ~/.ssh/id_ed25519
   

2. VSCode Configuration:

   • SSH Configuration: VSCode uses the settings.json file for configurations. Check if the remote.SSH.showLogin setting is enabled. If so, disable it to prevent password prompts.
   • SSH Agent: Ensure the SSH agent is running and properly configured. You can verify this using the ssh-add -l command. If your key isn't listed, add it with ssh-add ~/.ssh/id_ed25519.

3. Troubleshooting the SSH Agent:

   • Restart the Agent: If the SSH agent is misbehaving, try restarting it: eval $(ssh-agent -s)
   • Check Agent Socket: The SSH agent uses a socket file (typically /tmp/ssh-XXXXXXXX) to communicate. Make sure this file exists and has the correct permissions.
   • Check Environment Variables: Ensure the SSH_AUTH_SOCK environment variable is set correctly and points to the SSH agent socket.

Additional Value:

• Troubleshooting SSH Connections: For more in-depth troubleshooting, refer to the official SSH documentation https://www.openssh.com/ and the SSH agent documentation https://man7.org/linux/man-pages/man1/ssh-agent.1.html.

• Passwordless Login: With proper SSH key setup and configuration, you can enjoy passwordless logins to your remote servers, streamlining your development workflow.

Conclusion:

Setting up SSH keys for passwordless logins can seem straightforward, but small inconsistencies can lead to frustrating password prompts. By carefully reviewing the permissions, VSCode configuration, and the SSH agent, you can identify and resolve the issue.

Remember, a little troubleshooting goes a long way in keeping your development workflow efficient and secure!
