TouchID support for WebAuthn is the last thing I need to make the switch for my daily driver browser. I used Firefox for years, but being able to use TouchID for auth/MFA is just such a huge quality of life improvement for me that it keeps me on Chrome. Fortunately it looks like there has been at least a little movement on this recently (bumped from a P4 to P2) https://bugzilla.mozilla.org/show_bug.cgi?id=1536482
It still doesn't work on Mac or Linux.. FFS.
