I suggest y'all have a look at the FIPS-181 standard http://www.itl.nist.gov/fipspubs/fip181.htm It's an algorithm for generating random _pronounceable_ passwords, sort of the best of two worlds... Download and read the standard, if I'm not totally off, it even has a sample implementation by none other than Mr. Schneier.

You could also bugger up the 'randomization' of your passwords. Better to allow them to create their own passwords and make sure they are 'strong'. -- Michael On 4/15/05, James Barkley <James.Barkley () noaa gov> wrote:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A user authenticates with a username/passwd and you not only give the user the option to change his/her password any time they want but also make it mandatory that they change their password at least once every so often (e.g. 6 months). You know that users are not good at choosing good passwords, but you happen to have a good application module for generating random strong passwords. So, when the user is at the change password page and about to type in "Mets4Ever" as their new password, why not give them a list of 10 or so cryptographically strong, randomly generated passwords as suggestions for them. Assuming you are using https, then this seems like reasonable security... or am I missing something? - -Jim Barkley -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (MingW32) iD8DBQFCX2sJVtbq2E0xxN0RAu/qAJ9IniLfMUhKv2UpSweiXVfQn/wGRwCbBNQt zPNrsUoEcHrAlvIqbunriPM= =EYEs -----END PGP SIGNATURE-----
