Fix Microsoft Authenticator Number Matching Not Working for Power BI
Question details
The user is unable to receive or see number-matching prompts in the Microsoft Authenticator app when trying to sign into Power BI or Microsoft 365, often occurring after getting a new phone.
- Product
- Power BI / Microsoft Authenticator
- Device & OS
- not provided
- Scenario
- Attempting to sign in to Power BI or set up a Microsoft 365 trial using multi-factor authentication (MFA).
- Observed behavior
- The Microsoft Authenticator app fails to display the expected number-matching prompts, blocking access to the user account.
Ensure your mobile device has a stable internet connection and that notifications are fully enabled for the Microsoft Authenticator app in your device's settings.
Re-register Account and Enable Notifications in Authenticator
This is the most common fix if you recently replaced your phone or reconfigured your account, as security tokens do not automatically transfer.
When switching to a new device, the Microsoft Authenticator app needs to be explicitly re-linked to your work or school account to receive MFA push notifications and number-matching prompts.
Launch the Microsoft Authenticator app on your current mobile device and check if your Power BI or business account is actively listed.
If the account is missing or inactive, tap 'Add account' (the plus icon) and select 'Work or school account' to begin the registration process.
Navigate to your smartphone's system Settings, find the Authenticator app, and ensure all push notifications and lock screen alerts are turned on.
Go back to your computer and attempt to sign into Power BI or Microsoft 365 again to trigger the number-matching prompt on your phone.
Request a Microsoft Support Callback or Web Chat
If you are completely locked out and cannot re-register your authenticator app, you need administrative support from Microsoft to reset your MFA settings.

Frequently Asked Questions
Why did Microsoft Authenticator stop showing number matching after I got a new phone?
When you switch devices, the security tokens do not automatically transfer for security reasons. You must manually re-register your Microsoft account in the Authenticator app on the new phone to restore number matching prompts.
Am I considered a business user if I use the free version of Power BI?
Yes, generally, if your Power BI account is registered with a work or school email address, Microsoft treats it as a business account for support purposes, even if you are on the free tier.
What should I do if I cannot get past the Authenticator prompt to cancel a Microsoft 365 trial?
If MFA is blocking your access, you must contact Microsoft Support directly via their website and request a callback. Explain your login issue to the representative so they can assist you with account access and canceling the trial before your card is charged.
Can I use SMS or email instead of the Authenticator app?
If your organization's IT administrator has enabled alternative verification methods, you can click 'Sign in another way' on the login screen to choose SMS or email. If not, you must use the Authenticator app.
