Az első faktor a pin, amit a bitlocker állít be, a második a windows jelszó.
When BitLocker is enabled on a system drive and the PC has a TPM, you can choose to require that users type a PIN before BitLocker will unlock the drive. Such a PIN requirement can prevent an attacker who has physical access to a PC from even getting to the Windows logon, which makes it virtually impossible for the attacker to access or modify user data and system files.
Requiring a PIN at startup is a useful security feature because it acts as a second authentication factor (a second “something you know”).
