There is no session id.

Sessions in Flask are simply wrappers over cookies. What you save on it it's digitally signed and sent as a cookie to the client. When you make a request, that cookie is sent to your server and then verified and transformed in a Python object.

AFAIK, Flask-Login saves on the session the user ID.

To get total active connections, you can:

  1. At login, generate an unique id and save it on the session (flask.session['uid'] = uuid.uuid4(), for example), then save it on your database.
  2. At logout, delete that unique id from the session (del flask.session['uid']) and also from your database.
  3. Retrieve the count of active sessions using your favourite method (ORM/Raw SQL)
