3 stars: The app is decent, but it is in dire need of an interface update. Handling more than a handful of authenticators is tedious. Make it a grid with user configurable icons (and for the love of God, give us a few common ones by default) and show the code when we click on the grid item. Also, search. This app could be so much better.
4 stars: I'm only giving this app for stars because it could sometimes cause you to get in an endless loop and cause you to lose sleep until you finally get out of the loop. Buyer beware only for that issue otherwise the application being from Microsoft is a must have for some people but if you don't need it don't download it. Scott Styn
5 stars: Great app, idea, execution and optimization. You cannot screenshot it no matter how you try. It has got biometric and pin protection and cloud backup so you don't have to re-authenticate each and every website when resetting or switching device. Literally zero bugs, glitches or lack of features. Exactly what you would expect from Microsoft.
3 stars: Overall the app works as expected which is great. One issue. While using the Your Phone app on Windows 10 and connecting to my phone over wireless the Authenticator app shows a black screen. This does not happen with any other applications. I have also tried light and dark themes. This worked before and stopped working for a couple of months now.
4 stars: This app gives you codes and you do not have to wait until you recieve a code on SMS ...
