Mike Jones: self-issued

The W3C WebAuthn and FIDO 2.0 standards have won the 2019 European Identity and Cloud Award for Best Future Technology / Standard Project at the European Identity and Cloud (EIC) conference. This award recognizes the significance of these recently-approved standards, which enable password-less sign-in with platform authenticators, mobile devices, and security keys. They provide a huge step forward for online security, privacy, and convenience.

Thanks to Kuppinger Cole for recognizing the importance and impact of these important new standards!

I’m pleased to report that the IETF COSE Working Group has adopted the specification “COSE and JOSE Registrations for WebAuthn Algorithms”. An abstract of what it does is:

This specification defines how to use several algorithms with COSE [RFC8152] that are used by implementations of the W3C Web Authentication (WebAuthn) [WebAuthn] and FIDO2 Client to Authenticator Protocol (CTAP) [CTAP] specifications. These algorithms are to be registered in the IANA “COSE Algorithms” registry [IANA.COSE.Algorithms] and also in the IANA “JSON Web Signature and Encryption Algorithms” registry [IANA.JOSE.Algorithms], when not already registered there.

The algorithms registered are RSASSA-PKCS1-v1_5 with four different hash functions and signing with the secp256k1 curve. Note that there was consensus in the working group meeting not to work on registrations for the Elliptic Curve Direct Anonymous Attestation (ECDAA) algorithms “ED256” and “ED512”, both because of issues that have been raised with them and because they are not in widespread use.

The -01 version will address the review comments received on the mailing list from Jim Schaad and John Mattsson.

The specification is available at:

• https://tools.ietf.org/html/draft-ietf-cose-webauthn-algorithms-00

An HTML-formatted version is also available at:

• http://self-issued.info/docs/draft-ietf-cose-webauthn-algorithms-00.html

The new COSE working group charter includes this deliverable:

4. Define the algorithms needed for W3C Web Authentication for COSE using draft-jones-webauthn-cose-algorithms and draft-jones-webauthn-secp256k1 as a starting point (Informational).

I have written draft-jones-cose-additional-algorithms, which combines these starting points into a single draft, which registers these algorithms in the IANA COSE registries. When not already registered, this draft also registers these algorithms for use with JOSE in the IANA JOSE registries. I believe that this draft is ready for working group adoption to satisfy this deliverable.

I’m thrilled to report that the FIDO2 Client to Authenticator Protocol (CTAP) is now a published FIDO Alliance standard! Together with the now-standard Web Authentication (WebAuthn) specification, this completes standardization of the APIs and protocols needed to enable password-less logins on the Web, on PCs, and on and mobile devices. This is a huge step forward for online security, privacy, and convenience!

The FIDO2 CTAP standard is available in HTML and PDF versions at these locations:

I’m thrilled to report that the Web Authentication (WebAuthn) specification is now a W3C standard! See the W3C press release describing this major advance in Web security and convenience, which enables logging in without passwords. Alex Simons, Microsoft Vice President of Identity Program Management is quoted in the release, saying:

“Our work with W3C and FIDO Alliance, and contributions to FIDO2 standards have been a critical piece of Microsoft’s commitment to a world without passwords, which started in 2015. Today, Windows 10 with Microsoft Edge fully supports the WebAuthn standard and millions of users can log in to their Microsoft account without using a password.”

The release also describes commitments to the standard by Google, Mozilla, and Apple, among others. Thanks to all who worked on the standard and who built implementations as we developed the standard – ensuring that that the standard can be used for a broad set of use cases, including password-less sign-in with platform authenticators, mobile devices, and security keys.

The World Wide Web Consortium (W3C) has published a Proposed Recommendation (PR) for the Web Authentication (WebAuthn) specification, bringing WebAuthn one step closer to becoming a completed standard. The Proposed Recommendation is at https://www.w3.org/TR/2019/PR-webauthn-20190117/.

The PR contains only clarifications and editorial improvements to the second Candidate Recommendation (CR), with no substantial changes. The next step will be to publish a Recommendation – a W3C standard – based on the Proposed Recommendation.

W3C has published a second W3C Candidate Recommendation (CR) for the Web Authentication (WebAuthn) specification. The second Candidate Recommendation is at https://www.w3.org/TR/2018/CR-webauthn-20180807/.

This draft contains a few refinements since the first candidate recommendation but no substantial changes. The new CR was needed to fulfill the W3C’s IPR protection requirements. The few changes were based, in part, upon things learned during multiple interop events for WebAuthn implementations. The working group plans to base coming the Proposed Recommendation on this draft.

I gave the well-received presentation “Deprecating the Password: A Progress Report” at the May 2018 European Identity and Cloud Conference (EIC). The presentation is available as PowerPoint (large because of the embedded video) and PDF.

The presentation abstract is:

If you ask almost anyone you meet if they have too many passwords, if they have trouble remembering their passwords, or if they are reusing the same passwords in multiple places, you’re likely to get an ear-full. People intuitively know that there has to be something better than having to have a password for everything they do!

The good news is that passwords are being used for fewer and fewer identity interactions. They are being replaced by biometrics (sign into your phone, your PC, or your bank with your face or fingerprint), local PINs (prove it’s you to your device and it does the rest), and federation (sign in with Facebook, Google, Microsoft, etc.). This presentation will examine the progress we’ve made, the standards and devices making it possible, and stimulate a discussion on what’s left to do to deprecate the password.

Key takeaways are:

There are good alternatives to passwords in use today.
Passwords are being used for fewer and fewer identity interactions.
Devices are increasingly enabling authentication without passwords.
New standards are enabling cross-platform password-less authentication.
The days of having to use passwords for everything you do are numbered!

Thanks to Steve Hutchinson for this photo from the presentation and his vote of confidence.

The WebAuthn working group has published the “COSE Algorithms for Web Authentication (WebAuthn)” specification, which registers COSE algorithm identifiers for RSASSA-PKCS1-v1_5 signature algorithms with SHA-2 and SHA-1 hash algorithms. RSASSA-PKCS1-v1_5 with SHA-256 is used by several kinds of authenticators. RSASSA-PKCS1-v1_5 with SHA-1, while deprecated, is used by some Trusted Platform Modules (TPMs). See https://www.iana.org/assignments/cose/cose.xhtml#algorithms for the actual IANA registrations.

Thanks to John Fontana, Jeff Hodges, Tony Nadalin, Jim Schaad, Göran Selander, Wendy Seltzer, Sean Turner, and Samuel Weiler for their roles in registering these algorithm identifiers.

The specification is available at:

• https://tools.ietf.org/html/draft-jones-webauthn-cose-algorithms-01

An HTML-formatted version is also available at:

The W3C Web Authentication (WebAuthn) specification is now a W3C Candidate Recommendation (CR). See the specification at https://www.w3.org/TR/2018/CR-webauthn-20180320/ and my blog post announcing this result for the WebAuthn working group at https://www.w3.org/blog/webauthn/2018/03/20/candidate-recommendation/.

This milestone represents a huge step towards enabling logins to occur using privacy-preserving public/private key pairs securely held by authenticators, rather than passwords. Its contents have been informed by what we learned during several rounds of interop testing by multiple browser and authenticator vendors. The Web Authentication spec has also progressed in parallel with and been kept in sync with the FIDO2 Client To Authenticator Protocol (CTAP) specification, so that they work well together.

The W3C Web Authentication working group has published the seventh working draft of the W3C Web Authentication (WebAuthn) specification. See the release page for a description of the changes since WD-06. The working group plans for the next version published to be a W3C Candidate Recommendation (CR). No breaking changes are expected between WD-07 and CR.

The W3C Web Authentication working group has published the sixth working draft of the W3C Web Authentication specification. It now can request that the authenticator support user verification – meaning that it can be used as the sole or first authentication factor. It now also uses the standard CBOR COSE_Key key representation [RFC8152]. Like WD-05, implementation and interop testing for WD-06 is planned.
