Git Bash and 1Password SSH not working

in SSH

I've setup 1Password (the app and the extension) on a newly installed Windows 11 Pro. When attempting to do anything related to my SSH keys from within Git Bash I keep getting [email protected]: Permission denied (publickey) , however if I do the exact same action from within PowerShell or CMD everything works as expected.

I followed the setup guide that can be found here: https://developer.1password.com/docs/ssh

My .gitconfig is the following:

[core]
    editor = \"C:\\Users\\Svetlozar\\AppData\\Local\\Programs\\Microsoft VS Code\\bin\\code\" --wait
    sshcommand = C:/Windows/System32/OpenSSH/ssh.exe
[user]
    name = Svetlozar Redacted
    email = [email protected]

ssh -Tv [email protected] output:

When trying to look up for ways to resolve my issue I stumbled upon the following discussion https://1password.community/discussion/comment/634953#Comment_634953 where its mentioned that 1Password doesn't work within Git Bash, but then other discussions such as the one here: https://1password.community/discussion/127941/git-bash-always-wants-windows-hello-authentication seem to show that it is possible to make 1Password's SSH work with Git Bash.

The only relevant bit of the setup docs that I could think of which involves Git Bash is the following command: git config --global core.sshCommand "C:/Windows/System32/OpenSSH/ssh.exe" which I have ran and confirmed that the line is indeed added to the .gitconfig as seen above.

Does anyone have any idea what I could be missing or why it might not be working properly?

    The SSH agent should work with Git Bash. Could you run an ssh command again in git bash and check the logs of the 1Password app for any errors/messages? You can find the logs here %LOCALAPPDATA%/1Password/logs

    Hi, thank you for your response!

    After trying:

    The entire log from today looked like the following:

    Same commands in PowerShell worked just fine:

    PS C:\Users\Svetlozar> ssh-add -l
    256 SHA256:T885rgjU7HitHw+REDACTED/bY GitHub SSH Key (ED25519)
    
    PS C:\Users\Svetlozar> ssh -T [email protected]
    Hi REDACTED! You've successfully authenticated, but GitHub does not provide shell access.
    

    Nothing additional was added to the log. I can also see 1Password does start its SSH agent. I've also tried turning off the agent entirely (from 1Password's settings) and go through the setup process again with the same result (does not work in Git Bash but it works in PowerShell and CMD).

    I have now solved my problem! When installing Git one of the install options is if Git should install its own SSH agent or use the system one. Initially I had selected 'install its own' assuming that I can override it with the sshCommand setting but for whatever reason that setting didn't override it.

    I've re-installed Git with this option unticked this time and it all worked as expected.

    I'm happy to hear you have solved the problem and thanks for sharing your solution!
