Who wants a built-in browser native <login> and <federation> HTML element?

Here is one proposal on how to go about it!!

github.com/fedidcg/fede...

Any chance I know anyone that could get me closer to the substack engineering team? I'd love to hear from them what they are up to and how things are going for them!

@sphericalcowconsulting.com here is another part of the community, the at protocol developer community, which is also exploring using FedCM to facilitate parts of their flows. Any chance we can reach out to them and try to find some synergy?

@sphericalcowconsulting.com have we had the chance to reach out to the ActivityPub folks and try to connect the dots?

@sphericalcowconsulting.com just today I was browsing hackernews and clicked on a substack link and was surprised to see substack as a FedCM IdP :)

Kind of cool that they managed to put that together without ever reaching out to us!

TIL that we are still making progress on the `sudo` command line tool :)

Federated credential management · Issue #208 · web-platform-dx/developer-signals This GitHub issue is for collecting web developer signals for Federated credential management. The IdentityCredential API delegates authentication to a third-party identity provider, instead of usi...

if you're interested in #atproto getting a better sign-in flow in browsers, please give this a thumbs up. #FedCM also if u know more about how this would benefit you, leave a comment following their template! github.com/web-platform...

So a not too well known thing about me: I'm the co-author of the Client ID Metadata Documents internet draft that Bluesky / AT Proto uses for OAuth.

This document came about due to my work on Mastodon's OAuth implementation.

@willem.dobs.nl put together a pretty cool prototype and is starting to fire out PRs!

@thisismissem.social FYI

FediForum | Growing the Open Social Web:<br>An Online FediForum Un-Workshop

This seems pretty interesting!

Anyone going?

Sweet!!

Yeah, I think I arrived at the same conclusion, having spent a good 5-6 years in Google Search crawling JSON-LD.

I think the criticism is more general to the whole triples / graph notion, not just JSON-LD (e.g. applies to anything that is comparable to RDF).

We intend to make agentic login better for users!

@captaincalliope.blue any chance you know what's the status of this implementation?

Maybe @captaincalliope.blue can help get FedCM prioritized at Mozilla?

Any chance we can merge this prototype to the bluesky client and the common/shared PDS so that everybody else could use?

Sweet! @thisismissem.social @aaronpk.com @bnewbold.net @danabra.mov fyi

@captaincalliope.blue any chance you'd be interested in applying to a Google Summer of Code mentorship to find a student to help implement a baseline of FedCM in Firefox?

They just kicked off the program, and I applied for a couple for Chromium.

Any chance you would be able to apply to a Google Summer of Code mentorship, as part of the Blue Sky project or the ActivityPub community?

summerofcode.withgoogle.com/programs/2026

They just kicked off a call for projects and it is a great opportunity to mentor someone!

WDYT?

Something to note about the address/url bar is that it doesn't have a great analogy on mobile ... It exists, but much smaller surface area ...

Augment autofill with a `conditional` get · Issue #694 · w3c-fedid/FedCM There is a big intersection between the data that is available to FedCM and autofill, most notably, verified email addresses. Email addresses, in particular, are interesting because verifying them ...

Yeah, I think so.

Integration with autofill (as shown in this video) is already available in chrome canaries as this:

github.com/w3c-fedid/Fe...

Would that help?

Sweet! Whenever you get to it, just send it over and I can help you debug!

Maybe we can try the ActivityPub's Open Social foundation?

Maybe @aaronpk.com 's Auth0/Okta could pitch in?

I can ask internally if that would be possible, but I think that might murk the waters ... ideally, it would be driven by an independent institution ...

do you have a public link that i could use to try and debug?

Do you have a public link that I could use to try and debug?

Yeah, IIRC, I think you were worried about breaking users and website author's expectations? Was that it?

Expand a bit more?

For sure
