    Bitlocker on a non-TPM computer how secure is the password?


    I went thru the steps to enable bitlocker without a TPM module. I set it up to enter a password before bootup.
    Every thing appears to be working okay, but my question is just how secure is the password?! Is it stored on the hard
    drive unencrypted? How difficult would it be for a bad guy that has stolen my computer to hack it?
    Thanks
    Jerry

    BitLocker not requiring password at boot. (Without TPM)

    I've recently installed bitlocker on my computer. Although windows says my C: drive is encrypted; I am not asked for my decryption password when i boot the computer. I get put straight into the login screen. I've done the necessary steps to enable bitlocker without TPM but maybe i missed something. Help please.

    How to Use Bitlocker on Only Non System Drive and without TPM


    I want to use Bitlocker on my Non System E Drive without TPM. I read somewhere to do the following for without TPM:

    " Under Local Computer Policy navigate to Computer Configuration \ Administrative Templates \ Windows Components \ Bit Locker Drive Encryption \ Operating System Drives and double click on Require additional authentication at startup." and so on.

    but I am confused because the above note is mentioning "Operating System Drives " wherein I want to turn on Bitlocker on Non System Drive.

    Can we turn bitlocker "on" on Non System Drives without turning it "on" on System Drives and Can we turn it "on" on
    a Single Folder instead of Drive.

    Please advise step by step.

    Bitlocker without TPM

    Hi there,

    I'm trying to use Bitlocker without TPM

    My version is Windows 10 Home, and I try to follow -

    To turn on BitLocker Drive Encryption on a computer without a compatible TPM



    1. Click Start, type gpedit.mscin the Start Search box, and then press ENTER.
    2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
    3. In the Local Group Policy Editor console tree, click Local Computer Policy, click Administrative Templates, click Windows Components, and then clickBitLocker Drive Encryption.
    4. Double-click the setting Control Panel Setup: Enable Advanced Startup Options.
    5. Select the Enabled option, select the Allow BitLocker without a compatible TPM check box, and then click OK.
    You have changed the policy setting so that you can use a startup key instead of a TPM.

    1. Close the Local Group Policy Editor.
    2. To force Group Policy to apply immediately, you can click Start, typegpupdate.exe /forcein the Start Search box, and then press ENTER.
    3. Click Start, click Control Panel, click Security, and then click BitLocker Drive Encryption.
    4. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
    5. On the BitLocker Drive Encryption page, click Turn On BitLocker. This will only appear with the operating system volume.
    6. On the Set BitLocker Startup Preferences page, select the Require Startup USB Key at every startup option. This is the only option available for non-TPM configurations. This key must be inserted each time before you start
      the computer.
    7. Insert your USB flash drive in the computer, if it is not already there.
    8. On the Save your Startup Key page, choose the location of your USB flash drive, and then click Save.
    9. On the Save the recovery password page, you will see the following options:
    · Save the password on a USB drive. Saves the password to a USB flash drive.

    · Save the password in a folder. Saves the password to a folder on a network drive or other location.

    · Print the password. Prints the password

    While I have a problem on step 4.

    Double-click the setting Control Panel Setup: Enable Advanced Startup Options.

    I can find "BitLocker Drive Encryption" on my group policy editor, while I cannot find
    Control Panel Setup: Enable Advanced Startup Options anywhere.

    Thank you for your help.

    Best Regards,

    Yan
