Hi patrick G.D,

A BIOS update can sometimes affect the TPM information used by Windows Hello, which may cause the existing PIN to stop working. The PIN itself is specific to the device and is different from the Microsoft account password.

On the Windows sign-in screen, please select Sign-in options, choose the password icon, and try the password for the Microsoft account linked to the PC. If I forgot my PIN is available, you can also select it, but Windows will still require verification of the Microsoft account before a new PIN can be created.

If you no longer have access to the old email address or its security methods, use Microsoft’s Sign-in Helper from another device. It can suggest the appropriate recovery route based on the email address or phone number you enter. If you do not remember enough information for the recovery form, avoid submitting repeated guesses, as the account verification process cannot be bypassed.

Also check whether another administrator account appears in the lower-left corner of the Windows sign-in screen. If you can access one, you may be able to sign in and manage the old account from Windows settings.

Please note that this is a user-to-user support forum. Moderators and community contributors, including external Microsoft employees, do not have access to account records or Microsoft’s back-end systems and therefore cannot recover the account, remove its security verification, or unlock the PC remotely. My role here is limited to providing troubleshooting guidance based on the information you have shared.

I understand this may not be the outcome you were hoping for, especially when the PC is currently inaccessible. However, I want to be transparent about the available recovery options and avoid suggesting a method that could bypass Microsoft’s account-security protections.

If there is no other administrator account and the Microsoft account cannot be recovered, resetting Windows may be the remaining option. Before proceeding, please be aware that BitLocker may request its recovery key and that resetting Windows can remove applications or personal data, depending on the option selected. Do not clear the TPM or make further BIOS security changes, as doing so will not restore access to the old account. Thank you so much for your understanding.

Hi patrick G.D,

It has been a while and I am writing to see how things are going with this issue.

Have you had a chance to check the replies provided?

Any update would be appreciated.

Select Sign-in options on the Windows 11 sign-in screen and try the Microsoft-account password; the Windows Hello PIN is device-specific and is different from that password.^1^

A BIOS update can change or reset the TPM security information used by Windows Hello, causing Windows to require identity verification before creating a new PIN.^2^

Try these options in order

On the sign-in screen, select Sign-in options.
Select the password icon and enter the password for the old Microsoft account.
If available, select I forgot my PIN and follow the prompts. This option works for Microsoft accounts, but resetting the PIN still requires account verification.^1^
If Windows displays I don’t have any of these on the identity-verification screen, select it and replace the inaccessible email or phone information. Replacing all security information places the account into a restricted state for 30 days; the PIN can be reset after the new information becomes active.^2^

The old Microsoft account cannot simply be removed from the PC while it remains locked. Access must first be proven using its password, an existing verification method, or the security-information replacement process.

If the email address or account is uncertain

Use another phone or computer to run Microsoft’s sign-in helper. It can identify the appropriate recovery path for the email address or phone number entered.^3^

If the exact address was forgotten, Microsoft can show a masked username when a recovery phone number or email is available.^4^

If the account has not been signed into for more than two years, it might have been deleted and may no longer be recoverable.^3^ Since you may not remember enough information for the recovery form, do not repeatedly submit guesses; use the sign-in helper and the I don’t have any of these route if offered.

Last resort: reset Windows

If account verification is impossible and no other Windows administrator account exists, reset the PC and create a different Microsoft account:

At the sign-in screen, hold Shift.
While continuing to hold it, select Power → Restart.
In Windows Recovery Environment, select Troubleshoot → Reset this PC.^5^
Choose Keep my files first. It reinstalls Windows and removes installed applications and settings, but preserves personal files. Remove everything also deletes personal files.^6^
Complete setup using a new Microsoft account that you can access.

Important: If device encryption or BitLocker is enabled, Windows Recovery may request the BitLocker recovery key. Do not begin a reset until you understand the data impact; anything important should be backed up first where possible.^6^

Do not clear the TPM or change more BIOS security settings: the existing PIN is already unavailable, and those actions will not restore access to the old Microsoft account.
