If you forget the password for an OS drive
, fixed data drive
, or removable data drive
that you've encrypted with BitLocker Drive Encryption, or if something happens to your PC that prevents it from accessing the encrypted drive, you can still use a recovery key (a string of 48 random numbers) to get back into the drive using either BitLocker recovery
or the BitLocker Repair Tool
. You create a recovery key when you turn on BitLocker for the first time on each drive that you encrypt.
It's essential that you store a copy of your recovery in a safe place. If you lose it, you might permanently lose access to all of your files on the encrypted drive. You can store the recovery key by printing it, saving it on a USB flash drive, or saving it as a file on locally or on a network. While you can save your recovery key to another drive on your PC that you're not encrypting, it's best if you store it separate from your PC to prevent someone from easily using the recovery key to gain access to your PC.
This tutorial will show you how to back up the BitLocker recovery key
of an encrypted drive in Windows 8
to make additional copies for safe keeping.
