Implements login-methods.md §LM5 phase one. Core gains nostr/nip46.ts -- a Nip46Client speaking kind-24133 RPC with NIP-44 transport encryption, bunker:// parsing, nostrconnect listen (secret echo is proof-of-scan), auth_url surfacing, and typed deadline errors -- plus subscribeLive on RelayConnection with re-REQ on reconnect, and live post-EOSE delivery in the MockRelay so tests exercise real round trips against a fake bunker. The ephemeral client key and Nip46Client live in the crypto worker (§LM5.4); nip46* actions bypass the serial queue so a signer waiting minutes for human approval cannot block other worker calls, and the signer's auth_url reaches the UI as the worker's first notification frame. The widget's connect screen runs both legs at once: a nostrconnect QR -- rendered as dot-style inline SVG with rounded finder eyes, per owner preference -- for phone signers, and a bunker:// paste box (password input; the URI carries a token). window.nostr is now an element-routed provider, so a NIP-46 session claims the slot and hosts reading it get the remote signer transparently; NIP-07 still leaves the slot to the extension. Sessions stay thin per §LM7: no vault, no persistence. Persistence remains gated on the external vault review (§LM5.3). 14 new tests (core fake-bunker e2e, QR geometry, signer delegation) and two policy pins: bunker option below the password path, element stays web-storage-free.

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 noteslogin-methods.md— proposal: the widget as the single login surface, adding NIP-07 and NIP-46 sign-in behind the existing provider facade (nsec-paste login rejected on the record)
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 shipped 2026-07-30 in REVEAL mode
(requestNwcConnection, offerNwcConnection, and a Wallet-connections
screen). Durable per-origin grants and a Connected-apps page are still to
come; see connection-vault.md §19 for the open limitations.
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.
