![]() Press the Windows key + X on your keyboard and select Device Manager.(You can use BitLocker without a TPM chip by using software-based encryption, but it requires some extra steps for additional authentication.) ![]() Because TPM is at the hardware level, it can protect against guessing or automated dictionary attacks. For instance, when encryption is only at the software level, access may be vulnerable to dictionary attacks. A TPM chip enables your device to support advanced security features. To unlock a drive that is protected with BitLocker, anyone wanting access must enter a password or use a USB drive that unlocks the PC when it is inserted.īitLocker uses trusted platform module (TPM) hardware.
