After creating an account on ID My Team and installing the raspberry pi you should login to your profile and open your raspberry pi web panel by clicking on your Web Panel (Local IP) - in the same network as your pi. If there is no IP showing up your pi is either not connected to the internet or you have a firewall blocking it.
After logging in with your temporary name(root) and password you will be asked to enter your server Username and Credentials for the system.
Congratulations your system is now setup. For added security please create yourself a member profile and then delete the root profile.
