The user needs to resolve an issue where the Microsoft Authenticator app fails to display a verification code or push notification for a Microsoft 365 business account.

Fix Microsoft Authenticator Not Sending Verification Code for Work Accounts

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to sign in to a Microsoft 365 work account that requires two-factor authentication, but the Authenticator app is unresponsive.
Observed behavior: The Authenticator app does not generate a code or display a sign-in notification, and alternative verification options continuously loop back to the non-functioning app.

Before you start

Ensure your device has an active internet connection to receive push notifications and verify that your device's date and time settings are configured to update automatically.

Solution 1Recommended

Use Alternative Verification Methods

Attempt to use a fallback verification method, such as an SMS text, an email, or a phone call, if the default Authenticator prompt is failing.

Microsoft 365 accounts often have multiple backup authentication methods configured. If the primary app prompt fails, you can manually select a secondary option to gain access to your account.

Select an alternative sign-in method

On the Microsoft sign-in screen, click on 'Sign in another way' or 'I can't use my Microsoft Authenticator app right now'.

Choose your backup option

Select an alternative method from the list, such as a text message to your registered phone number or an alternate email address.

Enter the verification code

Retrieve the code sent via SMS or email and enter it into the sign-in prompt to access your account.

Looping Issue: If selecting an alternative method still redirects you to the Authenticator app, your account might not have backup methods properly configured.

Solution 2

Contact Your Organization's IT Administrator

Reach out to your company's IT support team to reset your multi-factor authentication (MFA) settings.

Frequently Asked Questions

Why is my Microsoft Authenticator app not receiving push notifications?

This can happen if battery optimization settings are restricting background activity for the app, if notifications are disabled in your system settings, or if your device lacks a stable internet connection.

Can I use Microsoft Authenticator without Wi-Fi or cellular data?

Yes. While push notifications require an internet connection to arrive, the Authenticator app continuously generates 6-digit one-time verification codes every 30 seconds that work entirely offline.

What should I do if I accidentally deleted my work account from the Authenticator app?

If your work account is removed from the app and you do not have a secondary verification method like SMS set up, you will need to contact your organization's IT administrator to revoke your current MFA sessions and allow you to re-register.

How do I back up my Microsoft Authenticator accounts?

You can back up your personal accounts by opening the Authenticator app settings and enabling 'Cloud Backup'. However, work or school accounts cannot be backed up this way and must be manually reconfigured on new devices.
