SSH2 Authetication with Public key and Password together

[SSH2]

I am using ganymed-ssh2 to connect to SFTP ( SSH2 ) server. I was able to use password authentication and public key authentication process successfully when used seperately.

Now the challenge is that I need to use both password and public key authentication together?

How do I do this?
