Azure Multi-Factor Authenticator App | HowTo | 3 of 3

Part One | Part Two | Part Three

Azure Multi-Factor Authenticator App: In Part One I covered:

• Why use Office 365 & Exchange Online with Azure Multi-Factor Authentication?

• Enable modern authentication in Exchange Online

• Office 365 & Exchange Online Multi-Factor Authentication in the Admin Portal

In Part Two I covered:

• Enrol Accounts for Office 365 Multi-Factor Authentication

Once Office 365 Multi-Factor Authentication has been enabled and the users enrolled it is sensible for your users to install the Microsoft Authenticator App. The App can be downloaded for a number of devices:

• Windows Phone: https://go.microsoft.com/fwlink/?linkid=823234
• Android: https://go.microsoft.com/fwlink/?Linkid=825072
• Apple iOS: https://go.microsoft.com/fwlink/?Linkid=825073

Once the Azure Multi-Factor Authenticator App has downloaded and installed on your device.
