 The account can be connected to multiple Apple devices which are represented as Things below the Bridge, see the example below.
 You may create multiple account Things for multiple accounts.
 
+If your Apple account has 2-factor-authentication enabled configuration requires two steps.
+First start by adding the Apple ID and password to your account thing configuration.
+You will receive a notification with a code on one of your Apple devices then.
