How to reset the password to factory default

After setting up my IoTaWatt i added a password but it doesn’t work. I guess I must have typed it incorrectly. Is there a way to reset the password to factory settings. I have pulled the SD card and copied the files to my PC if any information can be gleaned from those files.
Thanks for any help.

I would think the KGB could figure this out :grin: but all you need to do is delete the file
/iotawatt/auth.txt from the SD card.
