The Phase D surface from vault-ux.md, scoped to NWC and honest about its
boundary: an embedded same-origin widget cannot broker (§CV12.3), so the
API reveals, says so in its consent copy, and leans on the wallet-side
budget as the real security boundary.
One public call owns the whole ceremony. If nobody is signed in, the
sign-in flow runs first and the request resumes via the goto("dashboard")
hook exactly once; if the account has a connection bound to the
requesting origin, the user gets the one-tap approval screen the vault
exists for; otherwise a guided import -- Bitcoin Connect's wallet
chooser or a pasted URI. The BC integration lifts Satisfied's
production discipline verbatim: chooser only, lazy chunks (never
downloaded unless the flow opens), no numeric budget in
authorizationUrlOptions (the unit is not interoperable), disconnect and
clear bc:config so no plaintext copy outlives the ceremony.
The worker holds the vault root (never the sudo key -- wiped on
arrival) and gains vaultStatus/List/SaveNwc/FindForOrigin/RevealNwc/
SetBinding/Delete actions; the root rides the encrypted session cache
so restored sessions keep working, with a vaultEnabled marker so a
stale cache says "sign in again" instead of falsely claiming the
account has no vault. Publishing failures are loud -- a connection that
reached no relay is not saved anywhere and says so. The dashboard gains
Wallet connections management with "revoke app access" and "remove
from BitLogin" honestly separated from wallet-side revocation.
VaultSession gains buildDeletionRequest so the NIP-09 courtesy ask is
signed without exposing the signing key.

BitLogin Documentation
BitLogin is a static, relay-backed portable account protocol that gives users a familiar login name and password while preserving a user-controlled Nostr identity and independent phrase recovery.
This directory contains the core protocol specification, implementation notes, and experimental designs for expanding BitLogin into a portable account layer for compatible applications.
Core protocol
spec.md— canonical BitLogin protocol specificationsecond-factor.md— second-factor design notes
Portable account layer
These documents describe proposed capabilities that build on BitLogin's core identity and recovery model.
account-switching.md— multiple independent accounts on one device, fast switching, locking, logout, and account-aware signer behaviorportable-app-state.md— encrypted, user-owned application settings and lightweight state that follow the account across devicesportable-entitlements.md— discovery, verification, recovery, and presentation of purchases, licenses, memberships, and access rightsrelay-and-messaging-portability.md— relay-role management, DM inbox and outbox synchronization, sent-message recovery, and conversation reconstruction
Connection Vault
The Connection Vault stores portable application credentials outside the core
identity capsules as independently encrypted records. Its protocol layer
(records, key hierarchy, relay sync, migration, tiers) is implemented in
@bitlogin/core's src/vault/; the widget authorization layer (consent
UI, grants, Connected apps) is still to come.
connection-vault.md— overall vault architecture, key hierarchy, relay storage, authorization, recovery, and deletion; §18 records the implementation-time decisions (tier model, sudo key)vault-ux.md— the agreed user-experience walkthroughs, serving as the authorization layer's acceptance criterianwc-connections.md— Nostr Wallet Connect credential profile (parser/exporter implemented insrc/vault/nwc.ts)s3c-format.md— portables3c1:format for S3-compatible storage connections

Status terminology
Documents use these labels:
- Implemented — available in the current codebase
- Partially implemented — some required primitives or flows exist, but the complete user-facing feature does not
- Experimental design — documented for review and future implementation; wire formats and APIs may change
Experimental documents are not part of the stable BitLogin protocol until their schemas, security properties, migrations, and test vectors are finalized.
Recommended product sequence
A practical development sequence is:
- Complete the core account and messaging foundations.
- Add independent multi-account sessions and switching.
- Add relay management, inbox synchronization, and sent-message recovery.
- Add portable application state and per-app permissions.
- Add entitlement discovery and a portable ownership library.
- Implement the Connection Vault and its NWC and S3 profiles.
- Move high-value authorization into stronger extension, native, or cross-origin execution boundaries.
Design principle
BitLogin should coordinate portable identity, state, ownership, and service access without becoming the centralized custodian of the user's identity, money, files, messages, or purchases.
