5 stars: I'm very happy with the app. Using it for more than a couple of years. No need to worry about SMS and it's inherent security concerns. I've setup two factor authentication for my office account, multiple social media platform etc. It all works cool, simple and clean UI. I never changed my mobile since I installed it, hoping the backup option will help me to switch devices. I totally recommend.
4 stars: Works great and very simple to use. Product is used by the state agency where I work. Authentication is simple with the selection of one number on the authenticator app. Seems to me that more numbers should be shown on the app because I have a 1 in three chance of picking the correct number.
5 stars: Security matters in this unpredictable world, and with cyber attacks becoming more prevalent and user information being used for notorious means I'm happy in the knowledge microsoft is doing its part in keeping my information safe. Good job, and keep up the good work.
5 stars: Amazing, just brilliant! The app syncs your accounts with the cloud and to recover them you only have to remember one password!!! So all you need to do is to have one strong password for the recovery account, no more hassle about those countless passwords !!! The app itself is protected by fingerprint and/or PIN (your choice is what to use, you can just enter without any PIN or Fingerprint if you like to)! Bravo, Microsoft!
4 stars: Excellent but could use fewer clicks to perform auth...
