Adding Touch ID Support for MFA/password-less on Chromium (macOS)
Google has added fingerprint authentication on Chrome including support of Apple's biometric sensors "Touch ID" last year:
This seems to be implemented via Web Authentication API.
It would be awesome to use Touch ID as 2nd Factor or password-less option in Azure Active Directory. Currently you are able to choose between NFC and USB only (tested on lastest build of Chrome).
It would be even better if Edge Chromium supported the built-in fingerprint of MacBooks. :)
However, it seems to be a limitation of Azure Active Directory.
