Prompt (Keyboard interactive, "SSH server authentication"

We recently upgraded to WinSCP Version 5.7.2. Our FTP client required us to change the password for our account. I completed the change in our executable file but now I'm getting the following error in our logs when the batch script is ran via scheduled task. I have tried looking for all the places to get an idea of how to associate this via script but can't find anything. I appreciate any assistance.

Below is the log file.

I'm not really sure what you ask for.

You didn't specify any password in the script. So WinSCP cannot login.

I am not sure if this was the original poster's question or not...
But some sites do not require a password when you are exchanging keys...

That is the problem I am having... There IS NO password for the account... I can disable this check in the GUI... But have not found the correct option for "bypass-authentication"...

Anyone with ideas?

If you mean the Bypass authentication entirely, use a raw session setting SshNoUserAuth:
