 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).
