Once you're signed-in to SketchUp you’ll see a button in the SketchUp navigation bar at the top of the document window where you can Sign In or Out and manage your account. In addition to authorizing your subscription, signing in here will sign you into the Extension Warehouse and 3D Warehouse as well.
