New Authentication Standard Coming to Major Web Browsers

Web browsers from Google, Microsoft, and Mozilla will soon provide users with a new, password-less authentication standard built by the FIDO Alliance and the World Wide Web Consortium (W3C) and currently in the final approval stages.

W3C has advanced a standard web API called Web Authentication (WebAuthn) to the Candidate Recommendation (CR) stage, the final step before the final approval of a web standard. Expected to deliver stronger web authentication to users worldwide, it is already being implemented for Windows, Mac, Linux, Chrome OS and Android platforms.

W3C’s WebAuthn API enables strong, unique, public key-based credentials for each site, thus eliminating the risk that passwords stolen on one site could be used on another. WebAuthn can be incorporated into browsers and web platform infrastructure, providing users with new methods to securely authenticate on the web, in the browser, and across sites and devices.

Along with FIDO’s Client to Authenticator Protocol (CTAP) specification, it is a core component of the FIDO2 Project, which enables “users to authenticate easily to online services with desktop or mobile devices with phishing-resistant security.”

CTAP enables an external authenticator to transmit strong authentication credentials over USB, Bluetooth, or NFC to a device that has Internet access (PC or mobile phone).

Both WebAuthn and CTAP are available today, so that developers and vendors can implement support for the new authentication methods into their products and services. Backed by leading browser vendors, the new specifications should provide ubiquitous, hardware-backed FIDO Authentication protection to all Internet users.

“After years of increasingly severe data breaches and password credential theft, now is the time for service providers to end their dependency on vulnerable passwords and one-time-passcodes and adopt phishing-resistant FIDO Authentication for all websites and applications,” Brett McDowell, executive director of the FIDO Alliance, said.

Enterprises and online service providers can soon deploy the new web authentication standards to protect themselves and their customers from the risks associated with passwords. The new FIDO2 specifications complement existing password-less FIDO UAF and second-factor FIDO U2F use cases. All FIDO2 web browsers and online services are backwards compatible with certified FIDO Security Keys.

The standards are currently being implemented in major web browsers, including Chrome, Firefox and Microsoft Edge. Android and Windows 10 will have built-in support for FIDO Authentication, FIDO says.

The Alliance says it would soon launch interoperability testing and that it also plans on issuing certifications for servers, clients, and authenticators adhering to FIDO2 specifications. Conformance test tools have already become available on FIDO’s website.

A new Universal Server certification for servers that interoperate with all FIDO authenticator types (FIDO UAF, FIDO U2F, WebAuthn, and CTAP) is also underway.

Web apps running in a browser on a device with a FIDO Authenticator can call to a public API to enable FIDO Authentication of users. Developers can learn more on FIDO’s new developer resources page.

With FIDO2, users would benefit from both simpler — they would log in with a single gesture, using internal / built-in authenticators (such as fingerprint or facial biometrics in PCs, laptops and/or mobile devices) or external authenticators (security keys and mobile devices) — and stronger authentication — credentials and biometric templates never leave the user’s device and accounts are protected from phishing, man-in-the-middle and replay attacks that use stolen passwords.
