Unable to login to your computer as it is saying “Something happened and your PIN isn’t available” or “Your PIN is no longer available due to a change in the security settings on this device“? Windows Hello PIN is backed by a Trusted Platform Module (TPM) chip, so any changes with the TPM chip will result in the above error. If you see such error message while signing in to Windows 10, then you can follow this tutorial to resolve it.

How to Fix “Something happened and your PIN isn’t available” in Windows 10

To get started, just click on the Sign-in options beneath the error message “Something happened and your PIN isn’t available. Choose another sign-in option and set up your PIN again by going to Settings > Accounts > Sign-in options“.

Next, click on the key icon and try to log in to your local account or Microsoft account with a password. If you’ve forgotten your Windows 10 password, PCUnlocker Live CD can help.

After logging into Windows 10, open the Settings app and navigate to Accounts -> Sign-in options. Just select the Windows Hello PIN option and click on Remove.

Click on Remove again to confirm.

Enter your current password and click OK. This will remove your current PIN sign-in option immediately.

Reboot your computer. The next time you sign into Windows 10, just open the Settings app again and add a new PIN. The PIN sign-in option should be working now.

That’s it!
