Thanks. Note that I tried to write an accurate roadmap based on the discussion, but it was not the only roadmap I could've written – early stage, goals still to define. > There have been Persona extensions before for at least Firefox. It will probably be important to learn from them, even if I'm sure hardly anyone tried to use them. Do you know some? I only found https://addons.mozilla.org/en-US/firefox/addon/browser-sign-in/ https://addons.mozilla.org/en-US/firefox/addon/browser-sign-..., which is old (but new to me) and it seems defunct. I'm not sure whether the source code is accessible. https://www.youtube.com/watch?v=um0Ym-Yma8Y https://www.youtube.com/watch?v=um0Ym-Yma8Y looks nice though. Thanks for the hint to passwordless.net. A simpler fallback-provider might be exactly right, maybe even something for stage 1.5. The BrowserID protocol actually has a user certificate as endpoint. I'm not sure how and whether that is stored.
