Go to the official Microsoft account portal at https://account.microsoft.com/services and sign in with the account you used to buy the subscription.

Frequently Asked Questions

Why did Microsoft stop providing physical product keys for Microsoft 365?

Microsoft transitioned to digital licenses to simplify the activation process, prevent product keys from being lost or stolen, and allow users to manage their device installations directly from their centralized Microsoft account.

Can I transfer my Microsoft 365 digital license to a different Microsoft account?

No, a Microsoft 365 digital license is permanently linked to the Microsoft account that was used during the initial purchase or the account where the product key was first redeemed. It cannot be transferred.

What if I have multiple Microsoft accounts and cannot find my active subscription?

You should try signing into the Microsoft account portal (account.microsoft.com) using every email address you own. Check the 'Services & subscriptions' page for each account until you locate the active Microsoft 365 license.

Do I need a product key when renewing my Microsoft 365 subscription?

If you renew your subscription online directly through the Microsoft Store, you do not need a product key. The renewal is automatically applied to your existing digital license and updates the expiration date in your account.
