I put pronunceable passwords into a network authentication server about three years ago which had lots of office-type workers, not computer people. My goal: add some kind of psychological memory jog to help people remember them. Random strings no one remembers and most people write'em down. Fine! We'll do pronunceable passwords. I based it on the algorithm used by multics. They hated it and wrote 'em down. Now, years later I am a user of a multics system with pronunceable passwords, and I hate it! Yes, I've been tempted to write'em down. A better system is pass phrases which uses DES and a standard feedback chainning technique to develop a 64-bit result from a variable length phrase. A lot of password generation schemes beat the dictionary attack such as a few small words glued together with a number or other symbol. They are easier to remember than 8 characters of bizarre text.
