using verification code for AppleID on macbook air when connecting to iCloud
When i enter my appleID password to continue using iCloud (on my MacBook Air in the Sys Preference iCloud dialog), I get a dialog that says I need to enter a verification code. I hit the OK button. The code comes up on my iPhone. But then I can't find a place to enter the verification code on my MacBook Air in the Sys Pref iCloud dialog. I don't understand how to complete the password verification process. Where do I enter the verification code?
MacBook Air, Mac OS X (10.7.5), OS X 10.9.5
