   The recent Raspbian incarnations allow you to set the
   default user name during install, even encourage you NOT
   to use "pi".

   Of course "pi" is perfectly good IF you use a decent PW.
   For SSH, set very low limits on tries from one IP and on
   parallel login threads. I doubt you need to use a PI
   to handle all commercial internet traffic so you can
   be very anal about that stuff.

   Experiments CAN be enlightening  :-)

   Every so often I set firewall rule #1 to allow all - and
   log it. Just for five minutes or so of course. The results
   can be, well, "interesting" ...

   "admin" is the other common 'default' (sometimes irreplacable)
   user name on zillions of devices and apps.

   Again, use a decent PW or even more and you'll be OK.
