Once you have downloaded the app, please make sure you allow the Microsoft Authenticator app to use your camera when asked. If the app cannot use the camera, you will not be able to complete the setup correctly. Once the app is installed, you will need to set up your account to connect to the app.

Now that the app has been registered against your account, let’s validate that it has been set up correctly

Microsoft Authenticator notification

You will receive a ‘pop up’ notification from Microsoft Authenticator. You will need to press the Approve button to move forward. The nice thing is that, compared to SMS, MFA does not require you to type any number, making the process faster and easier.

If the setup is successful, you will receive the following confirmation: “Notification approved”

Now, you will set up a backup option: the normal MFA via SMS. You will be asked to enter your mobile phone number and decide if you want to have your validation done via an SMS or by having Microsoft call you.
