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

I’m pleased to report that a public Implementation Draft of the FIDO2 Client to Authenticator Protocol (CTAP) specification has been published. This specification enables FIDO2 clients, such as browsers implementing the W3C Web Authentication (WebAuthn) specification, to perform authentication using pairwise public/private key pairs securely held by authenticators speaking the CTAP protocol (rather than passwords). Use of three transports for communicating with authenticators is specified in the CTAP specification: USB Human Interface Device (USB HID), Near Field Communication (NFC), and Bluetooth Smart/Bluetooth Low Energy Technology (BLE).
This specification was developed in parallel with WebAuthn, including having a number of common authors. This CTAP version is aligned with the WebAuthn Candidate Recommendation (CR) version.
The CTAP Implementation Draft is available at:
Congratulations to the members of the FIDO2 working group for reaching this important milestone. This is a major step in our journey to deprecate the password!
