Verify Your Microsoft 365 Subscription Status
Check that the signed-in account owns an active, eligible Microsoft 365 Personal or Family license required by Microsoft Defender.
Microsoft Defender is not a standalone free app; it requires an active Microsoft 365 Personal or Family subscription to function properly. If your account does not have this subscription, or if it has expired, the app will throw an invalid license error.
Open a web browser on your tablet or computer and navigate to the official Microsoft account sign-in page.
Log in with your credentials, then click on the 'Services & subscriptions' tab in the top navigation menu.
Scroll through your active products to verify that a Microsoft 365 Personal or Family subscription is listed and currently active.
If you are using an organization or school account, you cannot manage this yourself. Contact your IT administrator to ensure you have been assigned the proper Microsoft Defender license.

Frequently Asked Questions
Can I use Microsoft Defender for free without a subscription?
No, Microsoft Defender for individuals requires an active Microsoft 365 Personal or Family subscription to verify your license and activate the app.
Why does Microsoft Defender tell me to contact my administrator?
This error occurs when you sign in using an email address provided by an employer or educational institution. Your IT department manages these licenses and must grant you access.
Is Microsoft Defender fully supported on Amazon Fire OS?
Amazon Fire OS is a modified version of Android. While you might be able to install Microsoft apps via third-party stores or sideloading, you may encounter activation errors if Google Play Services and Microsoft authentication frameworks aren't fully supported.
