Touch ID Icon has disappeared from System preferences
I have an iMac (24-inch, M1, 2021) with OS Monterey 12.4. My touch ID ceased working and when I opened the touch ID icon in system preferences all of the options were greyed out so I decided to delete my fingerprint in order to set it up again. After deleting the Touch ID icon disappeared from Systems preferences. I checked this forum and saw that with a M1 all you needed to do was to shutdown for for 30 seconds and restart to get the icon back. I have tried this and still no icon. I have logged in as another user and still no icon. How can I rectify?
iMac, OS X 10.11
