Someone asked how it works, so here's the writeup 👇

As mentioned, if you want to help us get tools like these in fandom's hands, you should support @fujocoded.bsky.social on Patreon www.patreon.com/c/fujocoded

Full post: www.tumblr.com/essential-ra...

Someone asked me how this work and "who is trusting who" with this type of authorization flow. Here's how it works:

The user is logged in to your website, using their PDS, which tl;dr is their personal data store in the ATproto network. Most people create theirs by making a Bluesky account, but there's other providers too. You can self-host one super easily, or move it across providers if you stop liking the one you have.

However you create or host it, the PDS logs in to your website through a OAuth flow. This is mostly the same as the one for any "login with X" services, and it only involves your site and the PDS itself.

Once their PDS is logged into your site, you know the visitor's unique identifier in the ATproto network. Then you use the Bluesky AppView (API) to see what the mutual relationship is between the logged in user and whoever you want (most likely you/the site owner).

If you want no third parties in the middle, you can also skip the Bluesky API and directly get the lists of Bluesky friends from your PDS and/or the one of the visitor. We just use the Bluesky AppView cause it's convenient, but there's really nothing stopping us from looking at the data directly.

Once you know their identity and your relationship, the hard part is done: if you follow them, you let them in; if not, they see the "unauthorized" page.

...and that's it!

It's really just:

I, site owner, need to know who you are in the network, please log in (only involves the site + the visitor's PDS/data storage)
Ok, now I know what your network identifier is, let me get a record of the people I follow in my own PDS/data storage (only involves the user's PDS, although you can use other APIs to help you)
You're in the list, see the page
You're not in the list, bye bye

Electric cars are fukkin' cool.

i'm on @atwork.place!

atwork.place/u/danabra.mov

🔵 For Hire

I'm offering consulting services with a focus on React and React Native.

I’m not writing code, but if you or your team need some technical guidance in UI engineering, I may be able to help. We can talk about your architectural challenges, performance challenges, dive deep into specific technical issues, or talk about higher-level approaches to product and infra development. I’ve been lucky to work with great engineers at both Meta and at Bluesky, and I enjoy the chance to pass on what I’ve learned.

The format is a 1:1 hourly call. We can do a single one at first, and extend to several sessions if you find it beneficial and/or want to follow up. This will probably work best for technical leaders (or very motivated learners).

If this sounds interesting, drop an email at dan.abramov.consulting@gmail.com, and I’ll reply if I can help.

Irrespective of that, people should learn towards oauth in ATproto particularly for the permission model it provides

👻HaunTed👻★ 韓聖安 @knowtheory.net · 13h

Are you stating a general opinion about app passwords, commenting on ATproto architecture, or asserting that I've made an incorrect value judgement about app passwords.

👻HaunTed👻★ 韓聖安 @knowtheory.net · 15h

Yep! They're also a Bluesky only thing. If you have an ATProto account outside of Bluesky you wouldn't be able to get an app password

'k, first piece of feedback: I'm not going to sign into things with app passwords. Happy to try things out w/ oAuth. If rolling your own oAuth setup is too much to tackle off the bat, you could also try @graze.social's AIP by @ngerakines.me, which maps PDS auth to OIDC github.com/graze-social...
