 Microsoft Authenticator Lite is another surface for Azure Active Directory (Azure AD) users to complete multifactor authentication by using push notifications or time-based one-time passcodes (TOTP) on their Android or iOS device. With Authenticator Lite, users can satisfy a multifactor authentication requirement from the convenience of a familiar app. Authenticator Lite is currently enabled in [Outlook mobile](https://www.microsoft.com/microsoft-365/outlook-mobile-for-android-and-ios). 
 
 Users receive a notification in Outlook mobile to approve or deny sign-in, or they can copy a TOTP to use during sign-in.

 By default, Authenticator Lite is [Microsoft managed](concept-authentication-default-enablement.md#microsoft-managed-settings) and disabled during preview. After general availability, the Microsoft managed state default value will change to enable Authenticator Lite. 
 
+### Enablement Authenticator Lite in Azure portal UX
+
+To enable Authenticator Lite in the Azure portal, complete the following steps:
+
+  1. In the Azure portal, click Security > Authentication methods > Microsoft Authenticator.
+
+  2. On the Enable and Target tab, click Yes and All users to enable the policy for everyone or add selected users and groups. Set the Authentication mode for these users/groups to Any or Push.
+
+  Only users who are enabled for Microsoft Authenticator here can be enabled to use Authenticator Lite for sign-in, or excluded from it. Users who aren't enabled for Microsoft Authenticator can't see the feature. Users who have Microsoft Authenticator downloaded on the same device Outlook is downloaded on will not be prompted to register for Authenticator Lite in Outlook.
