Microsoft Authenticator integrates directly with Entra ID (Azure AD), providing strong multi-factor authentication that aligns with Microsoft Secure Score recommendations.

Using the app rather than SMS helps protect users from SIM swapping, intercepted text messages, and basic phishing attacks that target one-time codes.

Authenticator also enables advanced scenarios such as passwordless phone sign-in, number matching, and conditional access policies that evaluate sign-in risk in real time.

How to set up a Microsoft 365 passkey before SMS and voice MFA retirement

Ask users to install Microsoft Authenticator from the official app store on their Android or iOS device and sign in with their work account when prompted.

Walk them through scanning the QR code presented during the "Set up your account" wizard in Microsoft 365, confirming that push notifications and biometrics are enabled.

Encourage users to register at least one backup method (such as a second device or a different factor) in case they lose or replace their primary phone.

For live training sessions or help-desk calls, you can share the dedicated Microsoft Authenticator setup page at /microsoft-authenticator.

That page includes platform-specific instructions, visuals, and a contact form that routes directly to the NTS support team for escalations.

Use it alongside your own enrollment campaign emails so users always have a single, trusted reference when they are asked to turn on MFA.
