Admin credentials can be used to sign in (log in) to your mobile app and the web GUI. They can be found on the sticker of the root Beacon.
If you are having any issues with your email address and password (if you have the ability to set up an account or haven't done so yet) this is an additional way to to log in.
This can only be used if you are connected to your Nokia WiFi network (LAN) and not all mobile app features will be available using this login. You are able to sign in with admin credentials if you Internet is down.
