Interesting -- for me pi-hole has worked for so long that I've forgotten my login even, but when I redo my home network in the near future I definitely intend to re-evaluate the options. Sounds like I've got 3 now...
This is also my issue with pi-hole, I still use it but I lost the password. Every now and then I take a crack at getting back in so I can update it. I have been thinking of switching to NextDNS so I could have blocking everywhere.
Other than this problem, Pi-Hole has always been great
