  • Windows Server 2008 and later

BitLocker provides there modes to encrypt the volume, including Transparent operation mode(TPM) based on hardware, user authentication mode such as a pre-boot PIN or password(so-called BitLocker password), and the USB Key mode which boots the protected OS via a USB device. You can combine more than one mode to enhance the security of your data.

When you enable BitLocker to encrypt your internal and external hard drives, it will automatically generate a BitLocker drive encryption recovery key, a unique 48-digit numerical password, and stored in a .BEK file. It is used to unlock/decrypt the BitLocker encrypted drive so that all the content is readable. If you lose it, you cannot access the BitLocker encrypted drive anymore.

When to use BitLocker drive encryption recovery key

Usually, computer users enter the PIN(Personal Identify Number) or password to unlock the device, and Windows loads the booting process to start up from the operating system. But if you have enabled the auto-unlock option in Windows 10, it causes the BitLocker keeps asking for the recovery key at every boot.

If so, you can disable auto-unlock by heading to the Start menu > Control Panel > BitLocker Drive Encryption, clicking the Turn off auto-unlock option next to the C drive, and restarting the computer.

In addition to that, many other reasons could also trigger the BitLocker recovery mode, showing a BitLocker recovery screen, and asking for the BitLocker drive encryption recovery key, including:

  • Authentication errors. Perhaps, you forget the PIN, enter the wrong PIN too many times, or lose the USB flash drive containing the startup key.
  • Boot/BIOS changes. When you upgrade BIOS, change the boot order, turn off BIOS support for USB when using a USB-based key to boot up the computer, etc., BitLocker will ask for the recovery key.
  • Hardware, software, and firmware changes. If you make changes to the primary NTFS partitions, upgrade TPM firmware, add or remove hardware, and so forth, you may need to enter the recovery key to access your data.

Some other situations could also make BitLocker ask for a recovery key as long as it detects a possible unauthorized attempt to access the data. You just enter your 48-digit recovery key to bypass the recovery mode and use your computer as normal.
