Can't log in to XB8

Up until recently, I've never had the need to log in to my XB8. This was a sealed in the box, new unit that I received last year. I've tried the ID & PW on the bottom of the unit along with 'admin & password'. Both are incorrect and after several attempts, it locks me out for 5 mins. I'm hoping to avoid doing a factory reset as I have numerous devices that would require set up again. Any help would be greatly appreciated.
