General availability: Microsoft Authenticator
Starting August 27, 2016, Microsoft Authenticator is the mobile application that will replace Azure Authenticator, the Microsoft account app, and all other Microsoft-published enterprise and consumer authenticator apps for Android, iOS, and Windows.
This new app quickly and securely verifies a customer’s identity online for all of their accounts. It provides Azure Multi-Factor Authentication for personal, work, or school Microsoft and third-party accounts through notifications or one-time passwords. Customers can use this app to register their devices with their company’s Azure Active Directory instance and get seamless single sign-on to mobile applications. Later in 2016, customers will also be able to use the app to unlock Windows 10 devices and sign in to Microsoft accounts without using a password.
