Just learned about the existence of #PuttyCAC and that (supposedly) the Putty project rejected implementing OpenSC smartcard support.
So now the only way you can use a smartcard (aka. a yubikey) for SSH authentication with #FileZilla and/or #WinSCP is to use it as both still do NOT support #OpenSSH agent but only the Putty Pageant.
So if anyone else is looking for a way to use their smartcard with WinSCP or FileZilla, install OpenSC, reboot, install Putty-CAC, start Putty-CAC|s pageant.
