If you allow more than 8 > characters, that number increases. If you're using md5 then there is no inherent restriction on what characters and number of characters that can be used in the password. The limitations are in the user, they'll probably use their phone number, DOB, dog's name -- anything that's easy to remember ;-) Hi, Okay with the followup above is there a way to handle a database table that will only allow certain characters for a password? (e.g. Only letters and numbers and not _';:)(*&^%$# etc...) I guess a easy managment way to do it is either via the PHP code or via JavaScript. Maybe more professional would be in the PHP code. Maybe the 'if' statement would be ideal? Any suggestions? Also while on php talk how do I make a java popup message appear in a PHP code? Is there a way to do this, alert? There are many ways to do it im Javascript but was wondering if PHP had a way to do it in the PHP code itself. (hidden away if possible) Jerry http://mobile.yahoo.com.au - Yahoo!
