The Authenticator app generates security codes you can use to help keep your Microsoft account secure. You can add your Microsoft account to the app by scanning a barcode or by manually entering a secret key. The app implements industry-standard security code generation and may also work with other services and providers. You can learn more about keeping your Microsoft account secure at

** The Authenticator app is not supported for use with Windows Azure Multi-Factor Authentication. Use the Mutli Factor Authentication app for this.

    Does what it needs to do, but would be nice if there was a URI scheme to automatically fetch the code for a login...or at least make the "copy to clipboard" a primary function with a button next to the account, rather than having to do the long press and tap.

    Excellent app which everybody should install.

    If I could give zero stars I would! App totally sucked

    Maybe you can add feature like access code to protect this app, and recover access code if we forget that. But it's very usefull.

    How many times do I have to enter the code before it authenticates? It keeps saying to check the number.
  • by User 10/19/2014
    Doesn't work, frustrating. Paired great no problems, entered code and .... wrong code. Repeat 20 times, always wrong. Can't delete the account from the phone to try and reset it, adding a new one says there is already a microsoft account with that login and the only thing I can do is cancel. Terrible UI and and UX for something so basic. Not functioning and now way to trouble shoot or get help.

    Great, very easy to use. Works with Google (I chose iPhone when enabling the authenticator in my G account). I would like an option to password protect the app, or use custom labels for each code. Right now if someone gets your phone they can see the codes AND the emails/accounts correlated with them (specifically Google lists the email address associated with the code). That's a problem.

    Almost perfect, just needs urgently the wp8.1 backup feature.
