All passwords are encrypted inside 68 Classifieds database. So if you have lost your administration password you have two options to generate a new one.
locate the “do_not_upload” directory in the bundle you originally downloaded after purchase.
upload the 'newpass.php' file to the administration directory of your site.
open a browser and visit www.yoursite.com/administration/newpass.php (make sure to replace “yoursite.com” with the domain name you're using. Also, if the classifieds script is installed in a subfolder, add that to the address.)
fill out the form on that page and submit the changes.
Please Note: You will be asked to verify your license key to submit the form
