Sorry, that was a typing error, you obviously can do that with a PIN. Which was the point I was trying to make.

I meant you can't reasonably change or revoke your fingerprints!

Changing your actual fingerprints, while possible, is usually painful and done accidentally.

(The best you can do is change from which fingers the prints will accepted. And at best, you only have a couple of handfuls of options there.)
