Well, depends on how precisely you "log in". If you'd use a DE that
pulls in a target on each new session then you'd get what you are
looking for (as suggested above). But if you don't then no, there's no
generic hook defined that allows you to start something based on
whether there is a session or not that'd work for all kinds of
sessions.

If you are interested in text sessions, then bash (or whatever you use
as shell) is the sesion manager, and that doesn't invoke such a target
either. That said, you could add "systemctl --user --no-block start
tty-login.target" or so to your .profile and then hook into that
target.

But no, there is no generic solution for this. Sorry.
