Windows Hello PIN

The PIN is not accepted

What it means

Windows Hello cannot verify the PIN, often after a TPM reset, an account change or a damaged Hello container.

Common causes

• TPM cleared or firmware updated
• The account password changed elsewhere
• The NGC folder that stores Hello data is damaged

How to fix it

1. Sign in with your password, then reset the PIN under Settings > Accounts > Sign-in options.
2. If the PIN option is missing, sign out and back in, then check Windows Update.
3. As a last resort, an administrator can delete C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC and set up Hello again.
4. Back up BitLocker recovery keys before clearing or resetting the TPM.
