Error 0x80090027 during Windows Hello PIN creation is listed as "Caller provided a wrong parameter." For this error, the documented guidance is to contact Microsoft Support for assistance.
Before escalating, try the standard PIN recovery steps that often fix Windows Hello PIN issues:
- Try creating the PIN again.
- Sign out, sign back in, and try again.
- Restart the laptop and try again.
- If the device is connected to Microsoft Entra ID for work or school, unjoin and rejoin it, then try again: Settings > System > About > Disconnect from organization
For the fingerprint prompt specifically: Windows Hello can fall back to PIN when fingerprint sign-in cannot complete. If fingerprint recognition is failing, sign in with a password if available, then re-register fingerprint data in: Settings > Accounts > Sign-in options > Fingerprint recognition (Windows Hello)
