Web Authentication API of WC3 or WebAuthn: Chrome, and Firefox will soon support a new Web Authentication API, which will provide greater protection against phishing attacks and reduce password usage.
The Web Authentication API of WC3 or WebAuthn promises a simpler and safer way to sign up on a page.
Instead of using the classic username with a password, the user will be able to register a fingerprint, retina or other biometric data stored on his smartphone.
The system will use an encrypted public key and ensure that each service that a user enters has its own key pairs, thus addressing the problem of reusing the same password.
With this API, one could visit a service page from his computer, tap the signup button, and then receive a notification on his smartphone asking him to sign up.
The person concerned should enter the authorization mode, which could be a PIN or a fingerprint that he will use in the future to log in to his account.
As recently reported by Nick Steele of Duo Security, WebAuthn is based on the oldest FIDO Alliance standard, called the UAF or Universal Authentication Factor, but it has many technical advantages.
So expect to see the new feature in Chrome and Firefox as mentioned above, but also in Microsoft's Edge trying to compete with the two major browsers.
Please note that although Apple's Safari Browser does not currently support WebAuthn, the Web Authentication Working Group has many developers of the company.
