The old AT&T router I had came with a pretty obscure SSID password on a label printed on the side of it. The admin password was also a mix of punctuation and mixed case alphanumerics. I saw a neighbor’s router and it’s SSID password was different. So if these were being machine generated and set, that means there’s some sort of service access and port into the router from AT&T’s side.
Comcast Business Router, however came with a fixed username and password which I had to change when I set it up. I can’t imagine a non-techie person going through this step.
I had Reader Mode installed but by the time I saw this posting, Chrome and Brave had already disabled it.
