tpm only encryption

The tpm only encryption tag covers discussions about BitLocker deployments that rely solely on a Trusted Platform Module without a PIN or USB key. Recent threads highlight how TPM-only configurations can be vulnerable to attacks like YellowKey and BitUnlocker, which exploit the Windows Recovery Environment to bypass encryption on physically accessed devices. These attacks demonstrate that while TPM-only encryption offers convenience, it may not fully protect against boot chain manipulation. The content focuses on security implications for Windows 11 and Windows Server systems, emphasizing the need for administrators to assess their BitLocker posture and consider additional protections beyond TPM-only encryption.
