TouchID not available after upgrade
I’ve just upgraded the iOS on my iMac to Ventura 13.2.1 and now Touch ID is unavailable. The option to log in with a fingerprint no longer appears on the lockscreen, just the password option appears. When I go to the settings, all the buttons are greyed out so they can’t be turned on but it looks like my fingerprints are still stored. I can’t find the padlock that used to be on each settings screen that had to be clicked in order to make changes. I am signed in to my Apple ID. I upgraded my work MacBook Pro at the same time and it is working fine. I have restarted the iMac but the problem remains.
iMac 24″, macOS 13.2
