A fully managed end-to-end service for digitally signing code, documents, and applications. (formerly Trusted Signing)
If you are locked out of your Microsoft Entra ID tenant and there are no other Global Administrators available, you will need to open a support ticket with Microsoft. The Data Protection Team can assist you in regaining access to your tenant. You can contact them for help with resetting credentials or claiming ownership of the tenant.
To initiate this process, you can find the appropriate support contact information for your region at the Microsoft support page.
