This is pretty sensible cybersecurity policy. Just don’t do what BT did on their HomeHubs and generate a brute forceable password based on a hash of the ssid and some serial numbers.
A lot of italian ISPs did that too in the early 2010s. Eventually someone figured out the algorithm to derive the WP2 passphrase from the SSID (and MAC address, I think) and wrote a handy tool. You were literally able to drive around a neighborhood and connect to any WiFi network you wanted.
