What Is BitLocker Drive Encryption on Windows 10?

BitLocker Drive Encryption is a built-in security feature in Windows 10 that provides full disk encryption. It ensures that unauthorized users cannot access your data, even if your device is lost or stolen. By encrypting the entire drive, BitLocker adds an extra layer of protection for sensitive information.

If BitLocker has been activated for your system drive, you must enter a password, PIN, or utilize a smart card to unlock it when booting up.

Upon plugging in an external hard drive or USB device encrypted with BitLocker, you need to unlock it to retrieve the data.

3. Following Credential or Device Alterations

In case you have updated your password, PIN, or replaced a smart card, you will have to re-authenticate using the new credentials to unlock BitLocker.

4. Recovering from a Forgotten Password
