login form

i've used a form written in html as logon page to a php and mysql based site. in the form i've used the method="post" attribute to send the variable to a php script that checks the username and password with the mysql userdatabase. my question is, is there another method that i can use in the form that will make the login more secure. isn't there something called http-post-vars or something like that.. any help apreciated regards Michael "Alle kan stave REX BOMBASA" http://bookmarks4all.cjb.net http://denandresiden.cjb.net http://www.geocities.com/zymosis2000
