Migrating from the Windows desktop standalone True Key app to the True key browser extensions only (Chrome, Firefox or new Edge) won't change the way you login to our app, you will notice now that even using the desktop app your True Key browser extension on the top right is signed in (blue icon) or signed out (black & red), and for instant login to work , your TK extensions needs to be signed in, this is the same that you would be required to do in order for auto fill to work using the extension only.
So in other words, as long as it is in blue, it means you are connected (logged in) and TK will work as expected.
