 Password Pro



This script uses a different approach to Password Protection. It still uses the password as the actual page, but it uses an encryption method that encrypts and checks the password. So if you fail to enter it correct after 3 times you go to a specific page (specified by the webmaster) and you don't get the annoying 404 page not found message as in other scripts. The password is password 

--------------------------------------------------------------------------------
 


Here is how to use the Password Pro on your own site. Just put the first code into a new HTML document. Load that HTML document and enter the password you wish to set. Then, put the second code into a new HTML document. Be sure to also change the code to your access code from the first script. Then, create the password protected page with the format [access password].html  



<!-- THREE STEPS TO INSTALL PASSWORD PRO:

   1.  Configure your access code with the script above.
   2.  Put the designated coding into the HEAD of document
   3.  Copy the final code into the BODY of document  -->

<!-- STEP ONE: Configure your access code with the script above!  -->

<!-- STEP TWO: Copy this code into the HEAD of your document  -->
