Safari 14, the version of Apple’s browser that will ship with iOS 14 and macOS Big Sur, will let you use Face ID or Touch ID to log in to websites built to support the feature. The functionality was confirmed in the browser’s beta release notes, and Apple has detailed how the feature works in a WWDC video for developers. The functionality is built on the WebAuthn component of the FIDO2 standard, developed by the FIDO Alliance. It should make logging into a website as easy as logging into an app secured with Touch ID or Face ID.
