 All notable changes to LazyBoy are documented here.
 
-## [Unreleased]
-
-Sign in with your own account. The shared install token is gone, and so are the
-model keys in the environment.
-
-- **Register and log in** with a username and password in the app. Passwords are
-  stored as PBKDF2-HMAC-SHA256 (120,000 rounds, per-password salt) and sessions
-  live in the database as token digests in an `HttpOnly`, `SameSite=Strict`
-  cookie. Repeated failures cool a username down for five minutes.
-- **One workspace per account.** Agents, chats, runs, schedules, credential
-  vaults, and model keys belong to the account that created them; a second
-  account on the same install sees none of it. Work created before this release
-  is adopted by the first account that registers.
-- **Model keys come from Settings → Models only.** `LAZYBOY_APP_TOKEN`,
-  `XAI_API_KEY`, `OPENCODE_GO_API_KEY`, and `OPENAI_API_KEY` are no longer read.
-  A workspace without a key does not quietly run on someone else's: the run
-  fails immediately and points at the setting to fix.
-- **`LAZYBOY_ALLOWED_HOSTS`** lists the domain names an install may be addressed
-  by (DNS rebinding guard). IPs and `localhost` keep working with no config.
-- Removed: the token login screen, `LAZYBOY_APP_TOKEN`, and the rule that a
-  non-loopback bind required a 32-character token. `SANDBOX_SUPERVISOR_TOKEN`
-  and `LAZYBOY_VAULT_KEY` are still required in `.env`.
-
-### 繁體中文
-
-改成自己的帳號登入：共享的安裝 token 拿掉了，環境變數裡的模型金鑰也拿掉了。
-
-- **在 App 裡註冊與登入**：密碼以 PBKDF2-HMAC-SHA256（120,000 輪、每組密碼各自的
-  salt）存放，session 在資料庫只存雜湊，cookie 是 `HttpOnly` + `SameSite=Strict`。
-  同一帳號連續失敗會冷卻五分鐘。
-- **一個帳號一個工作區**：Agent、對話、執行紀錄、排程、憑證庫與模型金鑰都只屬於
-  建立它的帳號，同一套安裝的第二個帳號看不到任何資料；舊資料由第一個註冊的帳號接手。
-- **模型金鑰只吃「設定 → 模型」**：不再讀 `LAZYBOY_APP_TOKEN`、`XAI_API_KEY`、
-  `OPENCODE_GO_API_KEY`、`OPENAI_API_KEY`。沒設金鑰的工作區不會偷偷用別人的金鑰，
-  任務會立刻失敗並指出該去哪裡補。
-- **`LAZYBOY_ALLOWED_HOSTS`**：要改用網域名稱連進來時列在這裡（DNS rebinding 防護）；
-  用 IP 或 `localhost` 不用設定。
-- 移除：token 登入畫面、`LAZYBOY_APP_TOKEN`，以及「綁非 loopback 需 32 字元 token」
-  的規則。`.env` 仍需要 `SANDBOX_SUPERVISOR_TOKEN` 與 `LAZYBOY_VAULT_KEY`。

The API listens on `127.0.0.1` by default, so set `LAZYBOY_BIND_IP=0.0.0.0` (or one network card's address) in `.env` and recreate the api container before a phone on your network can reach it.
