I installed my bbpress and all works fine, but then added a “secret key” to the config.php file after all was installed. It still works fine, but is that OK? Is my secret key doing what it is supposed to?

Secret key is used to calculate the cookies for password security. If you changed it, it just would mean everyone has to log in again, even if they did it just the moment before you changed it.

That should be the only effect.

Worst case senario that I can imagine is that people would find they can’t log in until they clear their cookies for your site. Should not happen in theory.
