Enable mobile app authentication with Azure Multi-Factor Authentication Server
The Microsoft Authenticator app offers an additional out-of-band verification option. Instead of placing an automated phone call or SMS to the user during login, Azure Multi-Factor Authentication pushes a notification to the Authenticator app on the user's smartphone or tablet. The user simply taps Verify (or enters a PIN and taps "Authenticate") in the app to complete their sign-in.
Using a mobile app for two-step verification is preferred when phone reception is unreliable. If you use the app as an OATH token generator, it doesn't require any network or internet connection.
As of July 1, 2019, Microsoft no longer offers Azure Multi-Factor Authentication Server (MFA Server) for new deployments. New customers that want to require multifactor authentication (MFA) during sign-in events should use cloud-based Azure AD Multi-Factor Authentication.
To get started with cloud-based MFA, see Tutorial: Secure user sign-in events with Azure AD Multi-Factor Authentication.
Existing customers that activated Azure Multi-Factor Authentication Server before July 1, 2019 can download the latest version, future updates, and generate activation credentials as usual.
If you have installed Azure Multi-Factor Authentication Server v8.x or higher, most of the steps below are not required. Mobile app authentication can be set up by following the steps under Configure the mobile app.
To use the Authenticator app, you must be running Azure Multi-Factor Authentication Server v8.x or higher
