Grandma Smith calls in because she changed her WPA2 password two years ago. Her grandson just bought her a new iPad and she can't connect. Tier I support says "I have your 'WiFi password' right here. It's hunter22." The call take 45 seconds and you're off to solve the next question.
Isn't it just better to have it always displayed, in a 40pt sized font, on some LAN-accessible Web page, reachable without authentication by default, so that the call center folk won't have to spend 2 more minutes telling Mrs. Smith that "yes, two is a number and hunter is in lowercase" but would rather simply point her to an URL?
