I was wondering when a reporter would uncover this.

So BitLocker is super secure, right? Well... BitLocker recovery keys are backed up to Microsoft's Cloud - and they give them out to law enforcement on request. Using the BitLocker recovery key, you can just unlock the device without a PIN etc.

Microsoft Gave FBI BitLocker Encryption Keys, Exposing Privacy Flaw

The tech giant said providing encryption keys was a standard response to a court order. But companies like Apple and Meta set up their systems so such a privacy violation isn’t possible.

From my knowledge, the following is true: sign in with MS account will store encryption key. It can be deleted. But is anything cloud really deleted?

Setting up computer as a local machine, from what I know, does not sync encryption keys. They change things frequently and I don’t trust MS, so still use caution.

Setting up a machine on Active Directory in an enterprise setting allows bit locker keys to be written to Active Directory, but I don’t believe it is enabled OOB.
