Need to cancel the Azure service I am being charged for but can't log into my account

Submit a signed-out Azure billing support request now and ask Microsoft to stop the charge by identifying and cancelling the inaccessible subscription; do not wait for account recovery to complete.

Submit the request while signed out

1. Open the signed-out Azure support request. Microsoft specifically provides this route for customers who cannot sign in to the Azure portal.^1^
2. Select the options closest to:
   • Product: Azure
   • Issue: Billing and subscription management
   • Problem: Cancel subscription / continued charges
3. State clearly:
   • This is a personal Azure account.
   • Access was lost because the Authenticator registration is unavailable.
   • No alternative verification method is available.
   • Charges are continuing and the subscription must be cancelled.
4. Provide privately through the support form:
   • Microsoft account email address
   • Latest invoice number
   • Approximate charge amount and date
   • Payment method’s last four digits, if requested
   • Subscription ID or billing-account details, if available from earlier invoices
   • A reachable email address and telephone number
5. Ask for both:
   • Immediate cancellation of the Azure subscription and billable resources
   • Identity/ownership verification instructions

Azure provides unlimited support for subscription-management matters, including billing and account transfers; a paid technical support plan is not required for this category.^2^

Do not post the invoice number, full payment-card details, account email, or other identifying information in this public Q&A thread. Q&A moderators cannot access or cancel subscriptions.

Recover the personal Microsoft account separately

Because all security information was lost, begin signing in and select I don’t have any of these at the Verify your identity prompt. Follow the instructions to replace the security information. Microsoft documents a 30-day waiting period before sign-in becomes available after all security information is replaced.^3^

This recovery path is separate from the signed-out billing case. Support agents cannot bypass personal-account two-step verification or directly change the account’s security details.^4^

If access is restored first

Cancel through:

1. Azure portal → Cost Management + Billing
2. Select Subscriptions or Azure subscriptions.
3. Select the charged subscription.
4. Select Cancel → Cancel subscription.
5. If prompted, select Turn off resources.
6. Turn off support-plan auto-renewal if one is associated and no other subscription uses it.
7. Confirm Cancel subscription.^5^

Cancellation stops Azure subscription billing immediately, although a final invoice can still include usage incurred before cancellation. Services are disabled after cancellation. Any separately purchased SaaS subscription might need to be cancelled manually; only pay-as-you-go SaaS subscriptions are automatically cancelled with the Azure subscription.^5^
