Wouldn't a native Windows tool be the native Win32-OpenSSH, rather than WSL?

Yes, I didn't realize that Windows has OpenSSH without WSL at the time of writing.

OK, now I understand what you were asking for.

My goal was to no longer use PuTTY as an external terminal for WinSCP and instead the already existing tools Windows 11 has.

For the key storage, I was trying to use keychain instead of Pageant, which I couldn't get to work.

As WinSCP would still require Pageant, I then tried to get it to work with Pageant.
So now I'm using a bridge between Windows Pageant and WSL2 (https://github.com/BlackReloaded/wsl2-ssh-pageant) and as terminal command.

This seems to work so far, but it's not the best solution as it still uses Pageant and using the Windows OpenSSH client would probably be even better (removing the overhead of WSL running).

I'm not sure what you ask for. Nor how is this released to WinSCP. Is this about WinSCP console window? Or what do you mean by "WinSCP ssh command"?

Hey,

did anyone find a way to be able to use the keychain installed in WSL for the WinSCP SSH command?

I have tried multiple different commands and wasn't able to get it to work. Keychain would always ask for the password, except I manually run the ssh command inside wsl.

Asks for a password:
