您已使用BitLocker To Go 加密您的闪存驱动器，现在您的数据不会被窥探。对于任何没有您密码的人来说，您的文件都是乱码，无法理解。不幸的是，如果您丢失了BitLocker密码，您的数据对您和其他人一样难以辨认。幸运的是，如果您在初始BitLocker配置期间保存了恢复密钥，您应该可以轻松解锁驱动器和抢救数据。驱动器解锁后，您可以更改密码以避免将来出现此问题。在本教程中，我们将向您解释如果您忘记了USB驱动器的BitLocker密码，您可以做的所有事情：
如果忘记密码，如何恢复BitLocker加密USB驱动器上的数据(USB)
如果您有一个使用BitLocker加密的USB驱动器，并且您不再记得它的密码，则只有一种方法可以访问它。您只能使用BitLocker 恢复密钥(BitLocker recovery key)来执行此操作。这是一个唯一的 48 位数字密码，由BitLocker在您加密该 USB 驱动器时(when you've encrypted that USB drive)为您创建。如果您忘记了密码，请按照以下步骤访问BitLocker加密的USB驱动器：(USB)
首先(First)，将加密的USB驱动器插入 Windows 10 计算机或设备上的USB端口，然后尝试使用文件资源管理器打开和解锁它(open and unlock it with File Explorer)。由于您不记得USB驱动器的(USB)BitLocker密码，请单击或点击更多选项(More options)而不是输入密码。
然后，BitLocker对话窗口应显示一个名为“输入恢复密钥”的选项。("Enter recovery key.")单击或点击它。
执行此操作后，BitLocker会要求您“输入 48 位恢复密钥以解锁此驱动器("Enter the 48-digit recovery key to unlock this drive)。”
根据您选择保存BitLocker恢复密钥的方式和位置，您可以在多个位置找到它：
- 在文本文件中
- 在您的 Microsoft 帐户中
- 在打印输出上
以下是每种情况下的操作：
如何使用文本文件中的USB BitLocker恢复密钥
如果在USB驱动器上激活(USB)BitLocker时选择将恢复密钥保存在文本文件中，则必须记住保存该文件的位置并打开它。从BitLocker 恢复密钥 [驱动器 ID].txt(BitLocker Recovery Key [Drive ID].txt)文件中复制恢复(Copy)密钥(Recovery Key)行。
然后，将BitLocker(BitLocker)恢复密钥粘贴到USB驱动器的BitLocker对话窗口中，然后按Unlock。
接受BitLocker恢复密钥后，您的闪存驱动器会在文件资源管理器(File Explorer)中自动打开。
如何从您的Microsoft帐户获取USB BitLocker恢复密钥
在USB(USB)驱动器上启用BitLocker后，您可能已决定将BitLocker恢复密钥保存在您的Microsoft 帐户(Microsoft account)中。在这种情况下，请使用 Web 浏览器登录您的Microsoft帐户并从此部分获取密钥：BitLocker 恢复密钥(BitLocker recovery keys)。如果您有多个使用BitLocker加密的USB驱动器，请找到您需要解锁的一个并复制其恢复密钥(Recovery key)。
从 Windows 10 PC将恢复密钥粘贴到BitLocker对话窗口中，然后按下解锁(Unlock)按钮。
如果BitLocker恢复密钥正确，BitLocker加密的USB驱动器现在应该会在(USB)文件资源管理器(File Explorer)中自动打开。
如何使用已打印纸张中的USB BitLocker恢复密钥
如果您在USB驱动器上打开BitLocker后决定打印恢复密钥，请查找那张纸。它应该如下所示：
在 Windows 10 计算机或设备的BitLocker(BitLocker)弹出窗口中键入完整的 48 位数字BitLocker恢复密钥。然后，按下解锁(Unlock)按钮。
如果您正确输入了恢复密钥，文件资源管理器(File Explorer)现在应该会打开您的加密USB驱动器。
使用新密码更改忘记的BitLocker USB驱动器密码
获得对BitLocker加密USB驱动器的访问权限后，您应该考虑为其创建一个新密码。否则，每次要使用加密驱动器时，都必须重新输入BitLocker恢复密钥。(BitLocker)要更改您忘记的BitLocker密码，请打开文件资源管理器(open File Explorer)，右键单击或按住USB驱动器，然后选择“更改 BitLocker 密码”。("Change BitLocker password.")
此操作会打开一个名为BitLocker Drive Encryption 的窗口，(BitLocker Drive Encryption,)在该窗口中要求您输入旧密码，然后再输入新密码。因为您不知道旧密码（您在这里的原因），所以您必须选择“重置忘记的密码”("Reset a forgotten password")选项。
输入(Enter)BitLocker加密USB驱动器的新密码，并确保您不会再次忘记它。输入密码两次后，点击Finish。
您应该会收到确认 BitLocker 加密的USB驱动器的密码已成功更改，就是这样！

您还可能忘记了使用BitLocker加密的(BitLocker)USB驱动器的密码及其恢复密钥。在这种情况下，坏消息是您拥有的数据将永远丢失。您唯一能做的就是格式化该USB驱动器并将其用作新驱动器。如果您需要帮助，请查看本教程：在 Windows 中格式化 SD 卡、USB 记忆棒或硬盘分区的 2 种方法(2 ways to format an SD Card, a USB memory stick, or a hard drive partition in Windows)。
您(Did)是否设法恢复了 BitLocker 加密的USB驱动器？

Get access to a BitLocker-encrypted USB drive when you forget its password
You've encrypted your flash drive using BitLocker Tо Go, and now your data is safe from prying еуes. Tо anyone without your password, your files are garbled beyond comprehension. Unfortunately, if you lose your BitLocker password, your data stays just as indеcipherable to you as it is to others. Luckily, if you saved the rеcоvery kеy during the initial BitLocker configuration, you should have no trouble unlocking the drive and rescuing your dаta. Once the drive is unlоcked, you can change your password to avoid this issue in the future. In this tutorial, we're gоіng to explain to уou еverything you can do if you forgot thе BitLocker password of a USB drive:
How to recover the data on a BitLocker encrypted USB drive if you forgot its password
If you have a USB drive that you've encrypted with BitLocker and you no longer remember the password for it, there's only one way to access it. You can only do it using the BitLocker recovery key. That's a unique 48-digit numerical password that was created by BitLocker for you when you've encrypted that USB drive. Here are the steps you have to take to access a BitLocker encrypted USB drive if you've forgotten its password:
First of all, plug your encrypted USB drive into a USB port on your Windows 10 computer or device and try to open and unlock it with File Explorer. As you don't remember the BitLocker password for the USB drive, instead of entering it, click or tap on More options.
The BitLocker dialog window should then show you an option called "Enter recovery key." Click or tap on it.
As soon as you do that, BitLocker asks you to "Enter the 48-digit recovery key to unlock this drive."
Depending on how and where you chose to save the BitLocker recovery key, you can find it in several places:
- In a text file
- In your Microsoft account
- On a printout
Here's what to do in each case:
How to use the USB BitLocker recovery key from a text file
If you chose to save the recovery key in a text file when you activated BitLocker on your USB drive, you have to remember where you saved that file and open it. Copy the Recovery Key line from the BitLocker Recovery Key [Drive ID].txt file.
Then, paste the BitLocker recovery key in the USB drive's BitLocker dialog window, and press Unlock.
Once the BitLocker recovery key has been accepted, your flash drive opens automatically in File Explorer.
How to get the USB BitLocker recovery key from your Microsoft account
When you've enabled BitLocker on your USB drive, you might have decided to save the BitLocker recovery key in your Microsoft account. In that case, use a web browser to sign in to your Microsoft account and get the key from this section: BitLocker recovery keys. If you have multiple USB drives encrypted with BitLocker, find the one you need to unlock and copy its Recovery key.
Paste the recovery key in the BitLocker dialog window from your Windows 10 PC, and push the Unlock button.
If the BitLocker recovery key was correct, the BitLocker-encrypted USB drive should now automatically open in File Explorer.
How to use the USB BitLocker recovery key from a paper you've printed
In case you've decided to print the recovery key when you've turned on BitLocker on your USB drive, look for that piece of paper. It should look like this:
Type the whole 48-digit numerical BitLocker recovery key in the BitLocker popup from your Windows 10 computer or device. Then, press the Unlock button.
If you've typed the recovery key correctly, File Explorer should now open your encrypted USB drive.
Change the forgotten password of the BitLocker USB drive with a new one
After you gain access to the BitLocker encrypted USB drive, you should consider creating a new password for it. Otherwise, you must re-enter the BitLocker recovery key each time you want to use the encrypted drive. To change the BitLocker password you forgot, open File Explorer, right-click or press-and-hold on the USB drive, and select "Change BitLocker password."
This action opens a window called BitLocker Drive Encryption, where you're asked for the old password before entering a new one. Because you don't know the old password (the reason you are here), you must choose the "Reset a forgotten password" option.
Enter the new password for the BitLocker encrypted USB drive and make sure that you don't forget it again. Once you've entered the password twice, hit Finish.
You should receive a confirmation that the password of the BitLocker-encrypted USB drive was successfully changed, and that's it!
TIP: If you'd rather disable BitLocker altogether for your USB drive, you can do that too. Just follow the steps from this guide: How to disable BitLocker To Go encryption and remove the unlock password.
What if I don't have the BitLocker recovery key for the USB drive? Can I get my data back?
There's also the possibility that you forgot both the password of a USB drive encrypted with BitLocker and it's recovery key. The bad news, in that case, is that the data you had on it is lost forever. The only thing you can do is format that USB drive and use it as new. If you need help with that, check this tutorial: 2 ways to format an SD Card, a USB memory stick, or a hard drive partition in Windows.
Did you manage to recover your BitLocker-encrypted USB drive?
Now that you understand how to rescue your data, even if you've forgotten your password, there should be little holding you back from protecting your data with BitLocker. If you keep your recovery key safe, you should never have any issues getting to your data. Try this helpful feature out and feel free to leave us comments about your experience or to ask questions.
