    Method 3. Turn ON the PIN Option through Registry worked for me.

    A solution I found on this page fixed my "PIN not available" error. Thank you! I was about to give up. I tried everything else and nothing worked until I found this page. I was able to make a change in the registry and that solved the problem.

    The solutions found on this page didn't work for me. It turned out that I had to disable TPM in the BIOS to get Windows Hello for Business (PIN and face) to start working again.
