ssh/sftp/scp/sudo/su/et al are all designed to stop you from injecting stored plaintext passwords. This is a subtle hint, written in mile-high flashing neon letters, that it's a really bad idea -- it's almost impossible to keep retrievably-stored passwords safe. "interactive password authentication" means "password typed by a human being in realtime authentication" and nothing else is supposed to do.

To this end, they read from the terminal, which your program doesn't control and not from standard input, which you can redirect. To even try to forcefeed it, you'll need to install a third-party brute-forcing utility like expect and write a big ugly script in it. It won't happen natively like keys do.

That's why they made the much safer key-based authentication, to remove the need and temptation to inject passwords.
