Finally taken the plunge and at first all was going ok, flashed the sd card, fired up Rasberry 4 HA, connected to router, joined the HA community, saw some discovered resources.Parked it for a while and when I returned tried to log in with username and password - I think these were OK but who knows, but got response Invalid username or password. I can’t see any obvious ways to reset these. I am using Imac and chrome browser. V disappointed to be lost at the first hurdle and seeking advice. I am a beginner without too much knowledge of programming etc. please help

I have managed to connect up keyboard and tv screen and am into cli connected directly but uncertain where to go from here. incidentally mouse doesn’t seem to operate although keyboard functional
