I know that true randomness only exists in nature. However, the randomization in PHP is fairly good. I have only used it on fairly small scales (i.e. Randomizing 200 quotes to give a random quote when people log onto a page.)
For passwords I have always gone an easier route. $password = time(); This will produce an impossible to guess string of numbers I think about 9 or 10 characters in length. I am sure others here will have better options. But this has worked well for me and is very very easy. <?php /* Stephen Johnson c | eh The Lone Coder http://www.thelonecoder.com [EMAIL PROTECTED] 562.924.4454 (office) 562.924.4075 (fax) continuing the struggle against bad code */ ?> > From: "J.
