TouchID doesn't work for Fast User switchiing in Ventura

It is suggested to start the below starting in the order that are presented and test after each step.

1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

2 - Safe Mode will also eliminate Third Party Software, extensions and drives from loading 

3 - Does the issue present in this mode ?

4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.

5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.

7 - Download the Application Etrecheck directly from the Developer.

This is a Diagnostic Tool that makes no changes to the computer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 

The application is free or paid from added features.

Found this on MacRumours:

"Go to System Settings/Privacy and Security-click on "Advanced" (at the bottom of the page) and de-select "Logout automatically after inactivity".

That should do it I think.

It is clearly a bug in the OS. Same here, since upgrading to macOS Ventura, Touch ID is not working to unlock the screen anymore.

But what makes me wondering, is that the issue was present since the Beta and yet not repaired in the release.

Yup, turning off "Logout automatically after inactivity" in Settings/Privacy and Security-bottom of screen, click on "Advanced", now my MAC mini unlocks with my Apple Watch or fingerprint all the time! Thanks Folks!

Using Touch ID in Ventura as per the link below

Use Touch ID on Mac

Except of above link

Use Touch ID to unlock your Mac, log in, or switch users

To use Touch ID for these tasks, you must have logged in to your Mac already by entering your password.

• Unlock your Mac and some password-protected items: When you wake your Mac from sleep, or open a password-protected item, just place your finger on Touch ID when asked.
• Log in from the login window: Click your name in the login window, then place your finger on Touch ID.
• Only user accounts that have passwords can be unlocked with Touch ID. Sharing-only users and guest users cannot use Touch ID.
• Switch users: Click the fast user switching menu  in the menu bar, choose a different user, then place your finger on Touch ID.
• To use Touch ID to switch to another user, you need to have set up fast user switching, and the user you switch to must have logged in to the Mac already by entering a password.

As the User ( you ) have assigned a " Best Answer " to another reply, this basically closes this question.

So an additional suggestions would become moot.

On the off chances, is this machine ruining the latest Version of Ventura version 13.1 ?

Touch ID was sparodic even after this. I have now disabled Touch on my second Account. See if this helps.

OK Folks, so I followed these instructions (boot up in Safe Mode) and now Touch ID is working ...most of the time. But my understanding is "A password is always required to log in. Your TouchID credentials are encrypted and securely stored. Typing the correct password is how you prove your identity to unlock them. After the first log in, TouchID will work until you log out or reboot." However after a while I need to use the password, even though I have not logged out, when touch ID/ Apple Watch log-in doesn't work.

Is there a setting for this or is this another part of the issue?

Going through this (above) fixed "Touch ID no longer working after upgrade to Ventura" on my MAC mini!

Thanks a bunch,

Gary

Having the same issue. Just updated to 13.2 and still not working.

Not working again. I agree, it’s clearly a bug. I paid $90 extra (inc. Tax) for numeric keyboard with Touch. I may apply for a refund!

Yes, only having the problem with Log-In. My Magic keyboard also went waky while updating a Contact. Turned it off and on, seems OK now.

disabling touch ID on second account made no difference!
