Another problem with "randomly" generated passwords is that
they are usually not as random as they appear to be.
The Morris/Thompson "Password Security: A Case History" ACM paper
(also in the standard UN*X documentation) discusses this.
As another example, a couple of years ago someone posted a generator
program that typically generated one of about 4000 different passwords.
That is not all that hard to break!

A good password generator program is certainly possible,
but I am still waiting to see one.

And then there is the problem with remembering them, as you say.
