Thank you for asking this question on the Microsoft Q&A Platform.
I understand that you need to know where your BitLocker recovery key is backed up.
The BitLocker recovery key is not stored at the endpoint.
In this article, you can find the options to store your BitLocker key https://support.microsoft.com/en-us/windows/finding-your-bitlocker-recovery-key-in-windows-6b71ad27-0b89-ea08-f143-056f5ab347d6
If you are a tenant administrator and the device is registered in your Azure AD, you can:
- login https://endpoint.microsoft.com/ as Global Admin, navigate to “Devices” – “All devices”, search your device label
- Click on your device, and in the “Monitor” session, you can find the “Recovery keys” option, click on it to see your recovery key
Hope this helps!
