What is required for a customer wanting to use BitLocker on a computer?

To use BitLocker for full disk encryption on a computer, a Trusted Platform Module (TPM) is typically required, which is a hardware component integrated into the motherboard. The TPM helps manage the encryption keys securely and ensures that data on the drive remains protected against unauthorized access. In scenarios where a TPM is not present, a USB key can serve as an alternate method to store the encryption key, thereby allowing BitLocker to be utilized while still ensuring a secure process.

The inclusion of a fingerprint reader, solid state or eSATA drive, or a smart card reader is not essential for BitLocker to function. While a fingerprint reader may provide an additional layer of security for user authentication, it does not directly impact BitLocker’s encryption capabilities. Similarly, the type of drive used (e.g., solid state or eSATA) is also irrelevant to BitLocker being activated; BitLocker can work with various types of storage devices, as long as the necessary key management, like that provided by a TPM or USB key, is available. Lastly, a smart card reader could facilitate user authentication but is not a prerequisite for enabling BitLocker encryption.
