cannot login using xampp as user

[ohforfuckssake]

iMac, 10.6 working as root. XAMPP 1.7.2 (latest for Mac I believe?)
I cannot access my local server 127.0.0.1, or localhost, through my browser since running the "/Applications/XAMPP/xamppfiles/xampp security" script.
The login window (which was not there before running the script) says:
The user name or password you entered for this area on 127.0.0.1:80 was incorrect.
Make sure you’re entering them correctly, and then try again.

xampp user

Your password will be sent unencrypted.

I used xampp as the user name as required, I only use one password for my internal server stuff but that did not work nor did trying to login as root or by a username...
All is well elsewhere. I can work on my sites (in htdocs), I can play in terminal but cannot figure out how to get past that login screen and I cannot get to phpmyadmin. Any suggestions would be welcome. Thank you
