Hi simon,
I understand why this would be frustrating, especially when you are only trying to set up a PIN for easier sign-in.
To narrow this down, could you please confirm a few details?
- Are you still able to sign in to Windows using your password or another sign-in option?
- Does the message show any error code?
- Did this start after a Windows update, device reset, or any recent account/security change?
- Is this a personal device only, or do you also have a work or school account connected under Settings > Accounts > Access work or school?
In the meantime, you can try these steps:
1, Make sure your Microsoft account password works first
- If you use a Microsoft account, try signing in to your account on another device/browser to confirm the password is correct. If the password was recently changed, restart the PC and try setting up the PIN again after signing in.
2, Use “I forgot my PIN” if it appears
- Go to Settings > Accounts > Sign-in options > PIN (Windows Hello) and check whether I forgot my PIN is available. If it is, use that option to verify your account and create a new PIN.
3, Check Windows Update
- Open Settings > Windows Update and install any pending updates, then restart the device.
4, Temporarily remove and re-add Windows Hello options
- If you have fingerprint or facial recognition already set up, remove them first under Settings > Accounts > Sign-in options, restart the PC, then try setting up the PIN again before re-adding fingerprint or face sign-in.
Wishing you a smooth setup and hope you can get the PIN sign-in working again soon. While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
