How to Auto Unlock BitLocker Drive in Windows

There is no need to unlock a BitLocker drive manually. Here is how to configure Windows to auto-unlock the BitLocker drive.

BitLocker is the built-in drive encryption tool in Windows. Since Windows 10, Microsoft started automatically encrypting all the drives in Windows with BitLocker if you are logged in with a Microsoft account. That way, even if the device is lost or stolen, no one can access the contents of a drive without proper authorization.

If you reinstall Windows while the drives are encrypted, you might have to unlock them with the BitLocker recovery key. Since the recovery is automatically backed up to OneDrive, you don’t have to worry about it in ‘most cases.’

By default, all drives that are automatically encrypted with BitLocker will be unlocked automatically as soon as you sign in to your user account.

However, if you manually encrypt a drive, you have to unlock it manually. The good thing is that you can configure BitLocker to automatically unlock a drive as soon as you sign in to Windows. That way, you don’t have to type a long and complicated BitLocker password every time. For example, this is particularly useful for things like USB drives, external HDDs, etc.

So, without further ado, let me show you how to auto-unlock BitLocker drive in Windows 10 and 11 operating systems.

The steps below work the same in Windows 10 and 11.

That is it. From now on, the BitLocker drive is unlocked automatically as soon as you sign in to your user account.

Remember that this setting only applies to your computer and when logged into the same user account you used to configure the setting. If the drive is plugged into another system or you are using another user account, the BitLocker encrypted drive will not be unlocked automatically. You have to use the BitLocker password or recovery key. The same is applicable when you reinstall Windows.
