As many online services have started to require two-factor authentication (2FA) we have distributed the Microsoft Authenticator App to all SMA iPads.
In a nutshell, once you set up the Authenticator App it will be used to verify your identify when you log into services like Microsoft (and others) on new devices and/or if you haven't used the service for a while. It is to help protect your information and keep people that may be trying to use your account from doing so. The Microsoft Authenticator App can be downloaded from the app store on other devices as well.
If you have any questions please Submit a request above or send an email to Tech Help @ SMA.
