Third-party cracking utilities are required to accomplish password bruteforcing in UNIX. Shoehorning it into a graphical login in Windows is even more difficult.
"Interactive password authentication" is supposed to mean "Password
typed by a human being in realtime authentication" and nothing else will do.

libssh2_userauth_password_ex
libssh2_userauth_password_ex(3) libssh2 manual libssh2_userauth_password_ex(3)
NAME
libssh2_userauth_password_ex - authenticate a session with username and password
SYNOPSIS
#include <libssh2.h>
int libssh2_userauth_password_ex(LIBSSH2_SESSION *session,
const char *username,
unsigned int username_len,
const char *password,
unsigned int password_len,
LIBSSH2_PASSWD_CHANGEREQ_FUNC((*passwd_change_cb)));
#define libssh2_userauth_password(session, username, password)
libssh2_userauth_password_ex((session), (username),
strlen(username),
(password), strlen(password), NULL)
DESCRIPTION
session - Session instance as returned by libssh2_session_init_ex(3)
username - Name of user to attempt plain password authentication for.
username_len - Length of username parameter.
password - Password to use for authenticating username.
password_len - Length of password parameter.
passwd_change_cb - If the host accepts authentication but requests that the password be changed, this callback will be issued. If no call-
back is defined, but server required password change, authentication will fail.
Attempt basic password authentication. Note that many SSH servers which appear to support ordinary password authentication actually have it
disabled and use Keyboard Interactive authentication (routed via PAM or another authentication backed) instead.
RETURN VALUE
Return 0 on success or negative on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
negative number, it isn't really a failure per se.
ERRORS
Some of the errors this function may return include:
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_PASSWORD_EXPIRED -
IBSSH2_ERROR_AUTHENTICATION_FAILED - failed, invalid username/password or public/private key.
