OSCommerce - How do I reset my admin password?
To reset the Admin password in newer versions of OSCommerce, you will need to do the following:
[1] Login to cPanel, and go to Databases -> phpMyAdmin
[2] Click on your OSCommerce database on the right
[3] On the next screen, click on the Administrators table
[4] Edit the record for the username in this table
Replace the contents of the password field with this, then click Go:

This will reset the password for your admin user to "pass". This is highly insecure and is only temporary until you are able to login to your OSCommerce Admin Area and reset the password again.
[5] Login to the Admin area of your OSCommerce, and then reset your password to something more secure.
