The purpose of this article is to walk through a typical sign-in experience.

What will your sign-in experience be?

Your sign-in experience differs depending on what you choose to use as your second factor: a phone call, an authentication app, or texts.


Sign in Options:

  1. Sign in with a phone call

  2. Sign in with a text message

  3. Sign in with the Microsoft Authenticator app ( NDX Recommends this method) ( this can be found in your phones App store)

  • Please note: for your phone app and server you will be asked to do this the first time, and only there after if you change your password.

  • Should you sign in with a web browser to view your mail you will be prompted each time to authenticate.

To sign in with a notification from the Microsoft Authenticator app

  1. Sign in to an application or service such as Microsoft 365 using your username and password.

  2. Microsoft sends a notification to the Microsoft Authenticator app on your device.

  3. Open the notification on your phone and select the Verify key. If your company requires a PIN, enter it here. You should now be signed in.

  1. To sign in using a verification code with the Microsoft Authenticator app

    If you use the Microsoft Authenticator app to get verification codes, then when you open the app you see a number under your account name. This number changes every 30 seconds so that you don't use the same number twice. When you're asked for a verification code, open the app and use whatever number is currently displayed.

    1. Sign in to an application or service such as Microsoft 365 using your username and password.

    2. Microsoft prompts you for a verification code.

    3. Open the Microsoft Authenticator app on your phone and enter the code in the box where you are signing in.
