How to register more than 3 fingerprints?

But, but, but, ..

the typical way Apple expects that to be used is used is to have up to three stored PER USER ACCOUNT, and for your spouse to have their own user account, which could ALSO have up to three stored for your spouse's account as well.

"For emergency use" of YOUR account, you spouse could enter the passcode.

MacOS is inherently a Multiple Users system, and that does not change if you choose to set up only one account and use it for all users. The features are there, ready for you to take advantage of.

Apple appeared to had made a design decision to limit the number of fingerprints to use with their devices. Whether or not, Apple will change this is unknown.

As such, I suggest that you submit your suggestion directly to Apple here: Product Feedback - Apple

Yes, yes, yes!

I also have more than three fingers.

The work that I do involves using the MacBook in a lot of locations, and while doing various other things.

I use my thumb when I'm working on my lap/standing, index at a desk, and middle when the computer is not directly in front of me.

So when I need to unlock the computer left-handedly, because the computer is on that side, or my right hand is trying to fix or hold something, I have to type in the password. It is such a pain!

Limiting to three fingerprints assumes a very static, desk-based use of the computer. Leave that for desktops!

10 fingers, please!

Also, I use the fingers of my 2 hands to connect to my computer and I want to give my wife the possibility to quickly connect to my computer when she needs it.

Great user feed back — Apple Feedback http://www.apple.com/feedback

why do you need more? do you leave your other hand at the office?

Great! Thanks for submitting your suggestion as I can see where it can be beneficial in a number of situations.
