Hi all, I am testing BitLocker with OS drive encryption. If I use TPM+ USB startup KEY + PIN code for startup authentication, can anyone knnow where is this PIN code stored. Is it stored in C drive if this drive is encypted? Besides, could this PIN code be manageed by IT administrator in enterprise domain environment? If not, does it mean that those who will use a same encrypted laptop need share this PIN code before they want to boot the system successfully? I'll be appreciate any help.

Hi Vincent, Thank you very much for your kindly response. As I understand according to your description, one computer has one PIN. And the hash of PIN actually saved in the encrypted volume. Therefore, who will use a same encrypted laptop need share to know this PIN code.
