Hello,
Thank you for posting in Microsoft Community forum.
Based on the description, I understand your question is related to need bitlocker recovery to be saved in Entra id.
Open the Group Policy Management Console.
Create a new Group Policy Object (GPO) or edit an existing one.
Navigate to Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption.
Enable the policy Store BitLocker recovery information in Active Directory Domain Services (AD DS).
Configure the policy to back up recovery passwords and key packages.
Have a nice day.
Best Regards,
Molly
