-### Identity & Sessions — Dual Authentication Model
+### Identity & Sessions — No Accounts
 
-The server supports two authentication paths: **anonymous sessions** for
-instant access, and **optional account registration** for multi-client access.
-
-#### Anonymous Sessions (No Account Required)
-
-The simplest entry point. No registration, no passwords.
+There are no accounts, no registration, no passwords. Identity is a signing
+key; a nick is just a display name. The two are decoupled.
 
 - **Session creation**: client sends `POST /api/v1/session` with a desired
   nick → server assigns an **auth token** (64 hex characters of
   cryptographically random bytes) and returns the user ID, nick, and token.
 - The auth token implicitly identifies the client. Clients present it via
   `Authorization: Bearer <token>`.
-- Anonymous sessions are ephemeral — when the session expires or the user
-  QUITs, the nick is released and there is no way to reclaim it.
-
-#### Registered Accounts (Optional)
-
-For users who want multi-client access (multiple devices sharing one session):
-
-- **Registration**: client sends `POST /api/v1/register` with a nick and
-  password (minimum 8 characters) → server creates a session with the
-  password hashed via bcrypt, and returns the user ID, nick, and auth token.
-- **Login**: client sends `POST /api/v1/login` with nick and password →
-  server verifies the password against the stored bcrypt hash and creates a
-  new client token for the existing session. This enables multi-client
-  access: logging in from a new device adds a client to the existing session
-  rather than creating a new one, so channel memberships and message queues
-  are shared. Note: login only works while the session still exists — if all
-  clients have logged out or the user has sent QUIT, the session is deleted
-  and the registration is lost.
-- Registered accounts cannot be logged into via `POST /api/v1/session` —
-  that endpoint is for anonymous sessions only.
-- Anonymous sessions (created via `/session`) cannot be logged into via
-  `/login` because they have no password set.
-
-#### Common Properties (Both Paths)
-
 - Nicks are changeable via the `NICK` command; the server-assigned user ID is
   the stable identity.
 - Server-assigned IDs — clients do not choose their own IDs.

-**Rationale:** IRC has no accounts. You connect, pick a nick, and talk.
-Anonymous sessions preserve that simplicity — instant access, zero friction.
-But some users want to access the same session from multiple devices without
-a bouncer. Optional registration with password enables multi-client login
-without adding friction for casual users: if you don't want an account,
-don't create one. Note: in the current implementation, both anonymous and
-registered sessions are deleted when the last client disconnects (QUIT or
