Windows Hello Keeps Asking for PIN: An Enduring Annoyance

If Windows Hello keeps asking for your PIN, you're not alone. This issue has plagued Windows users for years, and it can be incredibly frustrating. In this article, we'll explore the root causes of this problem and provide step-by-step instructions on how to resolve it.

Why Does Windows Hello Keep Asking for PIN?

There are several reasons why Windows Hello may continuously ask for your PIN:

• PIN Cache Corruption: The PIN cache is a temporary storage location that stores your PIN for quick access. If this cache becomes corrupted, Windows Hello may lose track of your PIN and prompt you to enter it again.
• Security Updates: Windows updates sometimes include security enhancements that can disrupt the PIN storage mechanisms. This can lead to Windows Hello forgetting your PIN.
• Hardware Issues: Issues with the fingerprint reader or webcam used for facial recognition can prevent Windows Hello from recognizing your biometric inputs.
• Third-Party Software: Some third-party software, such as antivirus programs, can interfere with the normal operation of Windows Hello.

How to Fix Windows Hello Asking for PIN

Here are the steps you can take to fix the "Windows Hello keeps asking for PIN" issue:

1. Reset the PIN Cache

• Open the Command Prompt as administrator.
• Type the following command: "reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\PINCACHE" /f
• Press Enter and restart your computer.

2. Re-register Windows Hello

• Open the Settings app.
