This is what my ISP does for their router/cable modem combo. There's a sticker that tells you the SSID, the password for the SSID, the URL for the web interface along with the user ID and password. The passwords are both randomly generated.

They will also put it into bridge mode for you where none of that stuff applies.

Yeah, mine as well, until recently they figured out that the passwords weren't so randomly generated as they were derived from the SSID. Great entropy...

I recommend to use a mnemonic password [1] and just print out the WiFi password (without using Google Cloud...) and use some adhesive tape to attach it on the bottom of the router. The downside is that someone who has physical access to the router can see the password within seconds. Someone's who's plumbing your drain or when you are on the toilet.

That they put it into bridge mode when you request is due to EU regulations where EU civilians have free choice of router.
