Hi WebKit-Dev, We've been working on a Web Platform API that allows users to login to websites with their federated accounts in a privacy preserving manner. We've been calling it FedCM (was WebID) and we would like to hear what you think! Here is our explainer, spec and a brief introduction: - explainer <https://github.com/fedidcg/FedCM/blob/main/explainer.md> - specification <https://fedidcg.github.io/FedCM/> - TPAC2021 <https://watch.videodelivery.net/29bab61e04e8cabf1517e5885c9fe4cf> presentation (video introduction) WDYT? One specific area of coordination is its relationship to the Login Status API and the Storage Access API. We'd be happy to learn more from you about both of these APIs and how they relate to FedCM, but just as a starting point, here [1 <https://github.com/fedidcg/FedCM/blob/main/explainer.md#the--login-status-api>, 2 <https://github.com/fedidcg/FedCM/blob/main/explainer.md#the-storage-access-api>] is our interpretation of each. Looking forward to hearing from you, Sam Various other past reviews: - WebID? <https://github.com/fedidcg/FedCM/issues/41> - WICG thread <https://discourse.wicg.io/t/proposal-webid-privacy-preserving-federated-sign-in-api/4661> - Federation and Browsers Workshop <https://github.com/fedidcg/FedCM/blob/main/meetings/2021/25-26_May_2021.md> - Intent To Prototype <https://groups.google.com/a/chromium.org/g/blink-dev/c/2B4TJ7j2U4M/m/1X5T3OszCAAJ> - FedID CG <https://www.w3.org/community/fed-id/> - early TAG review <https://github.com/w3ctag/design-reviews/issues/622> - Ready For Trial <https://groups.google.com/a/chromium.org/g/blink-dev/c/jlV_1m7uUAg> - spec TAG review <https://github.com/w3ctag/design-reviews/issues/718> - Mozilla's Standards Position <https://github.com/mozilla/standards-positions/issues/618>
