    BitLocker Setup- How Do I Disable the TPM and Use a Password Instead?


    I would like to enable BitLocker on my laptop, which has a TPM. However, I want to use a password instead of the TPM to decrypt the drive during pre-boot.

    I've tried disabling the TPM (using 'tpm.msc') and then enabling "Require additional authentication at startup" within the Group Policy Editor, but those steps didn't work.

    How can I disable the TPM and use a password instead? Alternatively, how can I keep the TPM enabled but also require a password (not a PIN) during pre-boot?

    Thanks!

    :)

  2. Bitlocker on my newer model laptop with TPM chip

    I am sorry but the link that you provided was of no use. My bitlocker is apparently working as it should on this Samsung S9 laptop which has a TPM chip, but no TPM module. I took it to a computer shop to discover that the module is missing. We also turned
    off bitlocker and the laptop decrypted in about 20 minutes. That is fast considering that there is 80GB+ data on its SSD hard drive.

    I am no happy that my laptop boots up directly to the Windows password screen. I need it to boot up the the bitlocker password screen first.

    Do I possibly need to change the settings on my TPM chip equipped (but not TPM module equipped) laptop as I did on my desktop PCs that do not have TPM chips? On those I changed the settings to authenticate without TPM.

    Please help me figure out how to make my laptop boot to the bitlocker password screen before proceeding to the Windows password screen.

    remove bitlocker encryption

    Hi Leon,

    I use a password to unlock the drive. You shouldn't have to use the recovery key to get in each time.

    That's what the Trusted Platform Module (TPM) device does is to store the encryption key for you so you don't have to enter anything. Do you have a TPM on your motherboard?

    I don't have any TPM on my computers so I just followed this article to enable Bitlocker in the Local Group Policy Editor and then I selected to use the password option:

    BitLocker Setup- How Do I Disable the TPM and Use a Password Instead?

    I can't tell you how anymore but I can tell you it can be done. A couple of years or so ago I was using bitlocker with a password on a MS Surface 1 which had TPM. I don't remember if I disabled the TRM but I do know I had to enter a bitlocker password to boot up (I am not thinking of the Windows password which was different). All I can say is read through the Group Policy Editor.

    Thanks. I've reviewed the Group Policy Editor and none of the options seem to be what I'm looking for. I don't mind leaving the TPM enabled, as long as I can also apply a password. The only option I see is to use the TPM with a numeric PIN. However, I want an alpha-numeric password, not a PIN.

    Any other advice?

    My password was alpha-numeric

    I dug out my Surface 1 and set up Bitlocker. I tried several combination in the Bitlocker area of the Group Policy Editor before iI got it working.
    1) Under "Require additional authentication at startup": A) Enabled, B) uncheck "Allow Bitlocker ...", and C) other 4 boxes all set to "Allow ...".
    2) Under "Enable use of Bitlocker authentication requiring preboot keyboard input on slates": "Enabled".
    3) Under "Allow enchanced PINs for startup": "Enabled"

    My desktop has the "orange bars" problem reported in other threads. The Surface 1 has the same problem but a blank blue screen instead of orange bars. I just blind type the password (it is alpha-numeric). If I make a mistake and Windows 10 does not come up, I press backspace a bunch of times then retype the password.
