Face ID could become even more useful thanks to a newly launched Web Authentication standard, which could replace regular web passcodes with biometric identification. This is via an API created by the FIDO Alliance and W3C. It allows users to access any online service in a browser through password-free FIDO Authentication.
While Apple already allows Face ID to autofill usernames and passcodes on iOS, this could go one step further by replacing the passcode altogether. This would make it a more secure option.
