Thanks Orly. I'm quite satisfied with the results from String::Random, I
think this would be sufficient. If my computations are correct, the
chances of duplication is something like 1 out of 676 million (random
username) and 1 out of 456.976 billion (random password). Combining the
two would be enough space :)

Quite random. But you can roll your own: use Digest::MD5 and base it on
the machine id of your machine. Or read /dev/urandom (Linux boxes
only) for some cryptographically secure random numbers. Of course
there's
a 1-in-2^128 chance of a hash collision (uhm, there are less protons in
the universe than that =)
