Fix Repeated Microsoft Authenticator MFA Prompts for Azure Subscription
Question details
The user is unable to complete the sign-in process for their Azure subscription because they receive two consecutive MFA prompts, and the second sign-in number fails to appear in the Microsoft Authenticator app.

- Product
- Microsoft Azure / Microsoft Authenticator
- Device & OS
- not provided
- Scenario
- Attempting to sign in to an Azure subscription that has Multi-Factor Authentication (MFA) enabled.
- Observed behavior
- After approving the first authentication request, a second prompt is triggered. The sign-in number for this second request does not display in the Microsoft Authenticator app, preventing successful login.
Verify that your mobile device has a stable cellular or Wi-Fi internet connection, is not in airplane mode, and has notifications enabled for the Microsoft Authenticator app.
Optimize Device Settings and Clear Browser Cache
Resolves sync and notification delays that prevent the second MFA prompt from appearing in the Authenticator app.
Network latency or corrupted browser session data can often trigger redundant authentication loops. By clearing your cache and ensuring optimal device settings, you can force the prompt to sync correctly.
Open your mobile device's settings, navigate to the app permissions for Microsoft Authenticator, and ensure that all notifications are fully allowed.
On your computer, open your web browser settings and clear the cache and cookies for all time. Alternatively, open a new Private or Incognito browsing window.
Restart your mobile device to refresh its network connection, and then attempt to log into your Azure subscription again from the cleared browser.

Use an Alternative MFA Sign-In Method
Bypass the app-based number matching issue by utilizing a fallback verification method like an SMS code or automated phone call.
Request an MFA Configuration Reset
Required if your Authenticator app registration is corrupted and out of sync with your Azure directory.

Frequently Asked Questions
Why does Azure prompt me for MFA twice?
Multiple prompts usually occur due to overlapping Conditional Access policies in Azure Active Directory, session timeouts, or moving between different services within Azure that require distinct authentication tokens.
What should I do if the Authenticator app doesn't show the sign-in number?
Open the Microsoft Authenticator app manually and pull down on the main screen to refresh. Also, verify that your phone's battery saver mode isn't restricting the app's background data and notifications.
How can I change my default sign-in method if Authenticator fails?
If you are able to sign in using an alternative method, navigate to your Microsoft account's 'Security info' page (mysignins.microsoft.com/security-info) to change your default sign-in method from Microsoft Authenticator to SMS or phone call.
