Platform authenticators for Web Authentication in Safari 14

Safari 14 will support platform authenticators for Web Authentication API (also known as WebAuthn). Current versions of Safari already support WebAuthn for security keys, such as YubiKey, which are called roaming authenticators, but soon you will be able to authenticate using Touch or Face ID on supported devices without any external keys; this is called a platform authenticator.

This is already supported by Chrome on Macs, but the importance of the new development is that millions of iOS and iPadOS users will be able to use WebAuthn without dongles.
