*Specification* Per TAG feedback, we broke the specification into two parts: An IETF backend specification here: https://dickhardt.github.io/email-verification/draft-hardt-email-verification.html And a corresponding W3C frontend specification which we will provide as we go through the Origin Trial and see the API design settle. *Demos* https://code.sgo.to/2024/10/25/verified-email-autocomplete.html *Summary* EVP (email verification protocol) helps users create, access and recover accounts by providing cryptographic proof of ownership seamlessly rather than email OTPs manually. It requires website authors, email providers and browsers to participate. *Blink component* Blink>Identity <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EIdentity%22> *Web Feature ID* Missing feature *TAG review* https://github.com/w3ctag/design-reviews/issues/1169 One of the main pieces of feedback was to take part of the spec to IETF (which would be able to assess parts of the proposal better), which we took by writing and circulating the following draft, as well as starting to find the appropriate groups for broader review: https://dickhardt.github.io/email-verification/draft-hardt-email-verification.html *TAG review status* We requested an early TAG review and got an "ambivalent". We will request another TAG review or reopen it as the design settles. *Goals for experimentation* There is much that we'd like to learn in origin trials, because there are multiple moving parts here. First, we'd like to gather evidence of developer demand and API fitness: is autocomplete a good entry point? what kinds of forms and UXs are out there? does the benefit developers get outweigh the cost of implementation? Second, we'd like to gather evidence if email providers are incentivized too. What's in it for them? Is the backend API appropriate? Third, we'd like to gather data on how users interact with the UX implementation: will users accept the prompt? do they expect the token to be shared during form submission or email selection? Fourth, we'd love to learn if other browsers empathize with the user and ecosystem pain too, and if the implementation choices we made are transferable to their architectures too. Fifth, more broadly, email verification is at the center of a lot of identity flows, so we'd like to learn how it might relate to other mechanisms, such as federation, phone number verification and password/passkey management. *Risks* *Interoperability and Compatibility* *No information provided* *Gecko*: Defer (https://github.com/mozilla/standards-positions/issues/1316) We filed for an early review before we had all of the information for Mozilla to make a proper assessment. We think we understand the proposal better now than we did 6 months ago, so we are planning to re-open the standard position request and try to offer some of the clarity that was lacking. *WebKit*: No signal ( https://github.com/WebKit/standards-positions/issues/578) We haven't formally gotten a review from Webkit, but we got some informal feedback last TPAC with their preference to augment WebOTP / one-time-codes and OTPs and activate IMAP clients (of which there are fewer) rather than email providers. We believe this alternative isn't necessarily mutually exclusive and can work symbiotically with what's being proposed. We expanded on that here: https://github.com/samuelgoto/email-verification-protocol#webotp-otps-vs-evts-and-imap *Web developers*: Positive This API requires participation by websites and email providers. We successfully ran a devtrial with a few partners which we expect will join us running an original trial. Based on what we heard so far, we are optimistic this will hit a sweet spot with website authors, but we'd like to gather further evidence of developer demand and API fitness in an actual production setup. *Other signals*: *Ergonomics* We think a declarative autocomplete API strikes the right balance for developers and users. There are a series of other variations that we have explored and are open to revisiting based on developer feedback that we listed here: https://github.com/samuelgoto/email-verification-protocol#website-api *Activation* This proposal requires incentivizing and changing websites, email providers, browsers and, to a smaller extent, user behavior. Much of the incentives are going to be pulled by the availability of email providers, which we think might be feasible to bootstrap. More on the economics here: https://github.com/samuelgoto/email-verification-protocol#activation-considerations *Security* https://github.com/samuelgoto/email-verification-protocol#security-considerations *WebView application risks* Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? *No information provided* *Ongoing technical constraints* *No information provided* *Debuggability* Still being developed. Basic error messages in the developer console available. *Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?* No. We are planning to start on desktop first and then introduce Android. We aren't sure if it would be possible/useful to support WebView. *Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* Not currently available. *DevTrial instructions* https://github.com/WICG/email-verification-protocol/blob/main/HOWTO.md *Flag name on about://flags* #email-verification-protocol *Finch feature name* *No information provided* *Non-finch justification* *No information provided* *Requires code in //chrome?* True *Estimated milestones* Origin trial desktop first 150 Origin trial desktop last 153 *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5205725253074944?gate=5146029401964544 *Links to previous Intent discussions* Intent to Prototype: https://groups.google.com/a/chromium.org/d/msgid/blink-dev/68bb77c8.050a0220.257801.0191.GAE%40google.com This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
