my room-temperature take is that you don't need a custom ROM to do this the same end result can be accomplished on stock android with an on-device "account vault" style app using a common API to communicate with other apps that support that SSO schema, no system access or custom ROM required

Happy Friday! I've been building towards an "Atmosphere OS", where my atproto account is the identity layer on a real phone. I wrote a little bit about it here:

On an Atmosphere OS - Scott's Thoughts
What if an Atmosphere account could handle email, groupware, and device-level identity without putting Google or Apple at the center?

ATProto User Intents Demo
This is a demo tool which allows atproto accounts to configure a reuse declaration for their public data. You can read more about this atproo mechanism in the "User Intents for Data Reuse" proposal from March 2025. Any account in the atproto network (including Bluesky accounts) can use this tool via OAuth. The source code for this demo is linked above.

At @roomy.space we've been cooking up the design for the next, ATProto-native iteration of Roomy, and that includes private data on protocol! The first component that we're working on is a group membership service that we're calling the "arbiter". Here's full overview of the design so far!

No Fork Required
scott.leaflet.pubShower thought idea: What about expanding the role of the PDS for account management? E.g. when signing up on atproto with any app/service for the first time, redirect to the already existing account interface (`/account/`) already present on reference PDS, making this flow mandatory to support.
I think there might be a need for a javascript library that implements the atproto repo minus the DID authentication and minus the PDS. Use case: being able to start a local-first app offline and cold without login and start creating records, then saturate with identity to sign+sync when online.
