    So easy to use, and I wish more sites supported this methodology. Any chance for an update with a transparent tile for WP8.1?

    Great app. Works well with Microsoft Accounts, Facebook, and Google. Needs a transparent live tile.

    With this one app, Microsoft AND YOU can make the Internet safe again. But if it's to be, it's up to you to install the app, and tell all your Internet Banks, Retailers, and anyone you do business with to EXPECT this technology. If you don't, people like you will continue to be plagued with the inhuman beings called cyber terrorists. You are either part of the problem or part of the solution!
