Observed behavior: The application requests a subscription payment or prompts for an upgrade to a paid tier (such as 'Authenticator Pro'), indicating it is likely a fake or third-party app.

Identify and Remove the Fraudulent Authenticator App

Since the official Microsoft Authenticator is free, a payment prompt means you likely downloaded a scam app. You need to uninstall it immediately and get the genuine application.

Many third-party developers create apps with names similar to 'Microsoft Authenticator' or 'Authenticator Pro' and use paid ads to appear at the top of app store search results. These apps charge expensive weekly or monthly subscription fees for a service that Microsoft provides for free.

Check the app publisher

Open your device's app store (Apple App Store or Google Play Store), search for the authenticator app you just installed, and check the developer name. The official app's publisher must be explicitly listed as 'Microsoft Corporation'.

Uninstall the fraudulent app

If the publisher is a third party or the app is demanding a subscription fee, go to your device's home screen or app settings, long-press the application icon, and select 'Uninstall' or 'Remove App'.

Cancel any active subscriptions

If you accidentally agreed to a free trial or payment, open your App Store or Google Play account profile, tap on 'Subscriptions', and cancel the active subscription for the fake app immediately to avoid charges.

Download the official app

Return to the official app store, search for 'Microsoft Authenticator', and look for the blue padlock icon published by Microsoft Corporation. Download and install this completely free version.

Security Warning: Never provide your Microsoft account passwords, backup codes, or personal credentials to a third-party application claiming to be an authenticator.
