As we informed, you about the Microsoft Authenticator was pushed in the iTunes and Google Play Store on Monday this week.
For new users, these new apps provide a single great MFA experience for both AAD and Microsoft consumer accounts.
Today, in a blog, the company providing some insights on push notifications and one-click approvals stated that in the Android version of Microsoft Authenticator, "push notifications are working for Azure AD and Microsoft accounts".
However, in the iOS version, the feature is kept in beta, as it ran into a few last minute bugs. The company however said, they're targeting to GA it before the end of August.
Thus the current iOS version supports push notifications and one-click approvals for Azure AD only right now.
If you'd like to join the beta test, you can send email to email@example.com and we'll get you added. (Be sure to send your first and last name along with your Apple ID in the email.)
Further, they says that the "TouchID on iOS" and "biometric fingerprint unlock on Android" are both working with the current version. However, the users are required to use a PIN to complete their Azure AD authentication. In this case, the "bio proof is used as an alternative to entering a PIN," explained Microsoft.
Additionally, the company stated they are working on to add a capability "to use biometric unlock features even if you don't have a PIN"—but "in the not too distant future".
Additionally, the Microsoft Authenticator for Windows phone is coming by end of this week—as they are completing localization.
