    Help! Whenever I try to download the app, this message pops up, "couldn't sign you in," "your username or password doesn't seem to be working, try entering it again." How can this be I just reset my password? I am fed up!!!!!!

    So easy to use, and I wish more sites supported this methodology. Any chance for an update with a transparent tile for WP8.1? Would be great if this worked like the Android Microsoft account app and prompt for approval to simplify process.

    This app is great. It also works with LastPass even though they only reference Google authenticator.
