emonPi login using WINSCP/SFTP: default password


I am bit shocked here, but I was trying to find a login for WINSCP. This video was actually advising this method if you want to add a picture to the dashboard (I still wonder how to add a picture to the online version of the dashboard!), it seems that the default credentials

username: pi
password: emonpi2016

Any idea where that is mentioned in the guidelines and how to change this? I was really struggling to log in, assuming the username was the same as logging in to the web-interface of emonPi local.

Silly me.
