Hi All, Let’s discuss how to start using Mobile Outlook App as MFA Authenticator App. Microsoft announces that the public preview of Authenticator Lite is now available! Anoop shared this on Apr 18, 2023, in YouTube short.
Let’s hope that the users will find the Lite version of the Authenticator app via the mobile Outlook app. This will help you move from a text message (SMS) and voice-based authentication. This new feature allows users to try a more streamlined version of the popular Authenticator app.
Strong authentication has become increasingly vital for protecting sensitive information. Because of that, Microsoft is excited to make this process even more accessible by embedding it directly into the Outlook client.
With Authenticator Lite, users can easily satisfy a multifactor authentication requirement from the convenience of a familiar app. Microsoft Authenticator app is trusted as a secure and easy way to authenticate, making it the most popular way to sign in with strong authentication in Azure.
What is Microsoft Authenticator Lite?
Microsoft Authenticator Lite is a supplementary tool available to Azure Active Directory (Azure AD) users, enabling them to carry out multifactor authentication on their Android or iOS devices through push notifications or time-based one-time passcodes (TOTP).

User Registration for Authenticator in Outlook
If you enabled Authenticator Lite, users are prompted to register their account directly from Outlook mobile. The multifactor authentication helps you access your accounts more securely. You can use Outlook to authenticate in two ways.
- Receive a push notification after entering your password online
- Use a TOTP (Time-based One-Time Passcode)
Note! – This is an important security enhancement for users authenticating via telecom transports. This feature’s Microsoft-managed setting will be enabled in May 2023. This will enable the feature for all users in tenants where the feature is set to Microsoft managed. If you wish to change the state of this feature, please do so before May 26, 2023.
After registering the Outlook authenticator, you will get a notification for multifactor authentication in the Outlook application itself. Users can now use multifactor authentication (MFA) for their work or school accounts directly through the Outlook app on their iOS or Android devices without downloading the Authenticator app separately.
The Outlook Authenticator Light provides the following.
- Users can easily secure their accounts with an additional layer of protection for free.
- Provide a more seamless and convenient experience for users who want to secure their accounts.
Note! – Rollout has not yet been completed across Outlook applications. If this feature is enabled in your tenant, your users may not yet be prompted for the experience. Microsoft recommends enabling this feature when the rollout completes minimizing user disruption.
