Too complicated for a noob like me to follow all the technicalities (hope I don't need to deal with them!). Anyway, all's well that ends well...
It's always a good thing to post such stories as a reminder to the rest of us... I just went to check if the password I have stored in various places, including good old paper, is the one starting with P. It is...

Oh, and yeah there are many incredible people ready to help out... my daughter went through a similar scare back when she was new around here and she immediately got help from people on Discord...
