Use -rawsettings SshNoUserAuth=1
See https://winscp.net/eng/docs/rawsettings

I even tried embedding -rawsettings AuthKI=0 in the code but same issue

While using sftp from SSIS I'm having terrible issue with password authentication. I'm executing it from my laptop and also WINCSP is on same laptop. I had been to the winscp application and changed the settings of the sftp site by unchecking "By pass SSH-Authentication entirely" and could connect via winscp session. But when executed via ssis I get below issue

here is my connection to sftp

/console /command "option batch abort" "open sftp://welcome:6s1+J<@ftp.XXX.XXX.com:22/" "get /foldername/*.csv c:\sFTPFILES\" "-log=C:\sFTPLOG\log.txt" "exit"

Is there a way to supply not to take keyboard authentication in above code?
