SSH setup on Windows - Permission Denied error

I've been working to set up my SSH agent with 1Password as per today's release on my computers. I was able to set it up on macOS, but Windows is giving me an issue where the ssh agent can't find the key generated by 1Password. Running the test command ssh -T [email protected] simply yields the [email protected]: Permission denied (publickey). error.

What's the best practice to set this up in the case where 1Password generated the ssh key?

GitHub does have my key. To be clear, this works on my macOS devices, but not on Windows.


1Password Version: 8.9.5
Extension Version: Not Provided
OS Version: Windows 11 Pro for Workstations
Browser:_ Chrome

    Could you provide the output of:

    ssh -vT [email protected]
    

    And of:

    ssh-add -l

    Certainly. The output is as follows:

    Hi there, any suggestions?

    Could you share your SSH config?

  • TallonRainTallonRain

    In the /.ssh config file:

    Host *
        IdentityAgent "~/.1password/agent.sock"

    Ah, that explains the error that you're seeing. In OpenSSH for Windows, the agent communication does not happen over a socket like it does on macOS or Linux, but over the \\.\pipe\openssh-ssh-agent pipe.

    This actually happens automatically, so you don't have set IdentityAgent in your SSH config. Could you try removing that snippet and run the SSH command again?

    Ah-ha, that did it. Interesting, I believe I added that erroneous config as a troubleshooting step, but as you say it's working automatically now that it has been removed. Thanks for the help!
