Windows 10: Bitlocker too many pin attempts, how long is it

Hi,I messed up the bitlocker pin, and when I typed in the right one it said "too many pin entry attempts, to reboot and try again press enter". So I did that, and whenever I enter the correct pin it says the same. I don't have the recovery key, because it's a corporate notebook.Will this message go away? If yes, then how long does it take to let me in with the correct pin again? Is there any way to log in with the correct pin?

Bitlocker with TPM startup key and PIN

Step 4 below shows how to set up BitLocker with TPM and PIN, but it doesn't use command line since using the UI is much easier.

BitLocker on Surface Pro 3 not working correctly

Hi JulianSchubert,

Thank you for posting your question in the Microsoft Community

TPM will lock itself out after a few incorrect authentication attempts. These could be due to incorrect PIN entry for BitLocker or incorrect PIN entry for TPM virtual smartcard PIN. For TPM version 1.2, the lockout behavior depends
on individual TPM manufacturer. For TPM 2.0, the specification states that the TPM will enter lockout after 32 incorrect attempts.

To terminate this BitLocker recovery loop, you need to suspend BitLocker within WinRE, I suggest you to follow the below steps.

Step 1:

1. Choose the “Skip this drive” link at the bottom of the page where you are asked to enter the recovery key. You should be presented with a menu that will let you get to a command prompt (The sequence is Advanced
   options -> Troubleshoot -> Advanced options -> Command prompt).
   
2. Once you have a command prompt,
   use the following command to check the BitLocker status of the C: drive:
   manage-bde -status c:
   
3. If the status is returned as locked, you’ll need to use the following command to unlock it using your recovery password:
   manage-bde -unlock c: -rp <your 48-digit recovery password>
   
4. Once the drive is unlocked you'll need to use the following command to suspend protection:
   manage-bde -protectors -disable c:
   
5. Then exit and reboot. The computer should now successfully boot Windows. Once there, use the BitLocker control panel to resume BitLocker protection.
   
6. You can reset TPM lockout using
   tpm.msc
   

Note: The recovery loop can occur for other reasons such as cases where TPM is disabled or malfunctions. You can still use the above steps to suspend BitLocker and boot Windows in such cases

Hope it helps.

 

Bitlocker Questions

Did you uncheck "Allow BitLocker without a compatible TPM (requires a password or a startup key on a USB flash drive)" in step 4?

Using "allow" is fine. You will specify using a PIN to unlock BitLocker at step 10.

It doesn't matter about your account password.
