When I try to use my fingerprint, it asks for my PIN; however, even though I enter the correct PIN, it returns an error—the error code is 0x80090027.

    Hi LÊ ANH TUẤN,

    Since restarting and re-registering the fingerprint have already been covered, I suggest resetting the Windows Hello PIN itself.

    1. At the sign-in screen, select I forgot my PIN and follow the verification prompts.
    2. If unavailable, choose Sign-in options > Password to sign in.
    3. Then go to Settings > Accounts > Sign-in options > PIN (Windows Hello) > I forgot my PIN and create a new PIN.
    4. After resetting it, test the PIN first, then fingerprint sign-in.

    I hope this helps. If error 0x80090027 still appears after creating a new PIN, please share where in the process the error occurs so we can narrow down the next step.

    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:

    1. Try creating the PIN again.
    2. Sign out, sign back in, and try again.
    3. Restart the laptop and try again.
    4. 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)
