X-sense homeassistant email logoff and logon with different email adress

I have the installation of x-sense Home Security with base SBS50 an approx. 15 XS01-M, all is working fine, but I made the misstake to use the wrong email adress. So I want to logoff and afterward to login again with different email adresse. I order to make the Homeassistant working and cooperating with the already installed Setup inside my WLAN. Is it possible to find out the location inside the config file or should I delete the installation and setup a brand new installation? How to do it, help would be great.
