Why does login say "Your Password is needed to enable touch ID" when TouchID is already enabled?

I'm missing something. Why can't you use TouchID?

The reason for asking is that I only see it on devices incorporating that capability.

Edit: Never mind, I just read IdrisSeabright's reply. I believe the time period is something in excess of 24 hours, but I've never timed it.

Yes, you can use TouchID to log in to your user account. I do it all the time. If, however, you're in the habit of turning off your computer when you've finished using it, you would need to use the password when you start it up again.

It would be less misleading if they did not even mention TouchID.

I agree the message could be more helpful, although I think should convey your inability to use TouchID until you provide your password.

The wording confused even me, hence my earlier reply.

What wording would you suggest instead? If it's more informative Apple might consider adopting it. Perhaps "Your password is needed to reenable Touch ID" but then I have to decide between "reenable" and "re-enable" 🤪

I like your minimalist approach.

You'll need to enter your password if you've restarted your computer or if you haven't logged in using TouchID in some period of time (12? 24? hours).

I suspect Apple may be working on the assumption that you will not be turning your computer off and will be using it often enough that this is rarely an issue.

Before the timeout period expires it says it says that you can use your password *or* TouchID to login. It is just being consistent.
