keyboard Authentication

We are using version 4.1.8.415 of WinSCP. I can log into the first login screen where it ask for: Host Name, User name and Password. We are using SFTP Protocol. At the next screen it requests a password for keyboard authentication. I have tried entering the previous password from the first screen and I have tried entering no password. Authentication fails. I cannot access the Advanced Site Settings to enable me to select the option to use the previous login.

First, you need to upgrade urgently. 4.1.8 is over 8 years old! It's not secure to use it!

Also, can you connect with any other SFTP/SSH client? E.g. PuTTY? Show us logs both from WinSCP (the latest version) and PuTTY (its event log).
