Frequently Asked Questions

Yes, you can use BitLocker without a TPM (Trusted Platform Module). Windows provides an option to use BitLocker with a startup password or a USB key as an alternative to TPM. This makes BitLocker accessible to devices that do not have a TPM chip or when the TPM is not activated.

BitLocker may have a minimal impact on system performance, but most users will not notice a significant difference. Modern processors are equipped with hardware support for encryption, which means that the encryption and decryption tasks be performed efficiently without noticeable delay.

Yes, you can share files with others as if your drive were not encrypted. Once you copy or move a file to another location, such as a USB drive or cloud storage service, it becomes automatically decrypted. The recipient does not need access to your BitLocker security to open the file.

Unfortunately, if you lose both your BitLocker password and your recovery key, there is no way to access the encrypted data. This emphasizes the importance of keeping your recovery key safe in a place where you can access it if needed.

BitLocker is designed to work seamlessly with Windows operating systems. If you want to open files on a non-Windows system, such as macOS or Linux, you must first decrypt the files or use third-party software compatible with BitLocker-encrypted drives. It is important to remember that the immediate purpose of BitLocker is to provide security within the Windows ecosystem.
