Building OAuth Authentication for ATProto apps: Part 1, the web use-case - Building on atproto
In this follow-up OAuth implementation guide I dive a bit deeper into the actual implementation details of building authentication for your web or mobile app that builds on top of ATProto.
atproto oauth2 vs. createSession, scope problems: (transition:generic vs. com.atproto.access) · bluesky-social atproto · Discussion #3211
Summary: When I authenticate via oauth2 on iPhone (via the blueSky page sheet that springs up ), I get an access token with "atproto transition:generic" scope. But passing that token to u...
OAuth for AT Protocol | Bluesky
We are very happy to release the initial specification of OAuth for AT Protocol! This is expected to be the primary authentication and authorization system between atproto client apps and PDS instances going forward, replacing the current flow using App Passwords and createSession over time.


here's my take on a minimal oauth browser client for atproto! no special API client class — just use plain `fetch` to make requests and a service worker automatically handles authorization headers/token refreshes/dpop retries/etc. (very experimental, not tested in production, use at your own risk)

tangled.orgnow updated my atproto oauth reference from last year! github.com/j4ckxyz/atproto-oauth-referen… - explains why to avoid `transition:generic` AND a skills file for your coding agent!!! github.com/j4ckxyz/atproto-oauth-referen… no reason to not have #atproto oauth anymore!

github.comtwo things can be true 1. `transition:generic` is too broad of scope for most atproto apps and users should be aware 2. `transition:generic` is pretty much all we got as atproto devs while more granular oauth scopes are being developed and users are fear mongering too hard too early rn

Clearsky has updated to require authentication when viewing who blocks a user, and the permission scope it's asking for via bsky's oauth is...absolutely wild. Way, way, way too many permission grants there, folks.
this would be my answer too, atproto oauth is unironically extremely based

i guess in a way this is the most widely used one, but also one that is severely underused in other ways. definitely identity. i've long been of the opinion that there are obviously cool things that come from public data and all the public pieces of the proto, but identity is higher impact.
I've been digging deep into what Elixir atproto OAuth can look like. This is not the final version yet, but it's starting to shape up. blog.annot.at/side-quest-an-elixir-atproto-…
