Right on! But what if you have a team of employees and interns that need access to different accounts. You can't expect them all to memorize unique passwords.

True enough. But all they'd have to memorize is one hard password (or even a pattern like 102938), and one modifier pattern based on the URL of the site.

A simple example, using 102938 as the base password would be taking the main name part of the url (eg. www.google.com would just be "google"), converting each letter to a number (g = 7, o = 15, o = 15, g = 7, l = 12, e = 5), adding them all together (61), divide that by the number of characters used (61 / 6 = int(10.16) = 10), then add that result to every pair of numbers in the original password (10 + 10 = 20, 29 + 10 = 39, 38 + 10 = 48), giving you a password of 203940 for that site :)

EDIT: forgot to make this hard to crack. Again, the pattern approach can work - 203948 for "google" could easily and predictably become "go20og39le48@mycompany" or some such.
