"Apple’s Face ID and Touch ID have made it easier for users to log into their mobile devices like iPhones and iPads and on some Macs offering the Touch ID button. Now Apple is bringing Face ID and Touch ID to the web. At the company’s virtual Worldwide Developers Conference this week, Apple introduced a way for web developers to add support for Face ID and Touch ID to their websites, allowing Safari users to log in without having to enter their username and password.
In a WWDC session aimed at web developers, the company showed off the new functionality, which Apple touted would provide a “frictionless experience” for users.
Similar to how Face ID and Touch ID work today in iOS apps, web developers who choose to implement the new technology could prompt their users to choose a biometric authentication method the next time they visit their website."
