Once you download GuardedID® a “G” appears in the Dock. Four variations explain when GuardedID® or Apple is protecting you as you type on the keyboard: a red exclamation point (!), a green dot (.), a red dot (.), and a green dot (.) with a white dash. (See other Knowledge Base articles for explanations of each.)
A red exclamation point means GuardedID® is not activated at that time. Go to “Menu | Manage License” and enter your license activation key if the field is blank; click “Activate”.
