Alright, I solved it with auh_interactive_dumb() method. but I don't need SFTPClient(used for file transfer) I only need ssh client for command execution. so what is difference inactual?

Hey manikanta, I am connecting to jump server which is asking password and passcode. first password gets verified then it ask passcode (code in form of digits coming from authenticator app) . I tried your solution for this but later when I tried to execute commands, it gives me following error: bad authentication type ; allowed types: [ 'publicke y', 'gssapi -keyex', 'gssapi - with -mic', 'passwor d'] further I need to execute commands and it also show transport has no option to execute commands. could you please figure it out? I found one answer parallel from stack overflow its similar sitution but when I debug paramiko it shows authentication (password) failed , I am new user so can't share stack overflow link but I am sharing title of question below: Paramiko: password + sms-passcode autentification
