No, a human does not have access to your password.

For the purposes of machine learning we can do something like this: as a request passes through us see if it's a POST to /wp-admin or similar, see if the response is 200 or 302 (which would tell us if the login worked or not). All that's done by code not people. Use that as a label "good login" or "bad login" and then see if there are lots of "bad login" events for certain characteristics and use that to predict what's a bot.
