    Great to have security feature. Would be nice if it would copy the code for easy pasting. Some apps, like Bing Rewards, switch away from code prompt screen when switching between apps.

    App works great, and love that I can use 2 factor auth to keep my account more secure!

    Convenient and secure way to get security codes than the traditional methods.

    Write some fricking instructions boneheads!!!!!!!! Took a while to figure it out. For example the QR code can be scanned by the Authenticator app, you don't have to go find another program to do that, and once it sets up, the bar will show progress and numbers change, and now you are complete, you can close the app. Thanks for the app MSFT but write some fricking instructions!
