I have same dialog prompt now after an OpenSSH server has started to ask the 2FA code based on TOTP. I can enter this code in GUI, but I cannot pass it to my script. Now my script logs the following (please see last two lines):
I have my verification code calculated properly based on http://blog.tinisles.com/2011/10/google-authenticator-one-time-password-algorithm-in-javascript/ but I have no idea how to reply to this server's second prompt from the script.

keyboard-interactive authentication and console command line in WinSCP
Hello,
I use WinScp and use console. I copy files with command like this: It works correctly.
Recently the ssh server began to require keyboard-interactive authentication, as shown in the picture. Through the GUI I insert code and everything will connect successfully.
Is it possible to enter this verification code through the console? Сan you give examples?
Thank you in advance!

exit.
