chore: update version to 1.6.0 in package.json and app-version.ts

- Add fallbackKdfIterations parameter to completeLoginWithVaultKeys
- Save offline unlock record (email, profile, profileKey, kdfIterations)
  when completing vault-key-based login, ensuring offline unlock works
  after passkey (PRF) authentication
- Pass through fallbackIterations from performPasskeyLogin caller
- Add .reasonix/ to .gitignore

+# NodeWarden Passkey 登录研究记录
+
+记录日期：2026-06-09  
+研究范围：NodeWarden 自己的 server、web 登录/注册链路，以及官方 Bitwarden server、web、browser extension 对账户 passkey 登录的实现方式。
+
+## 结论先放前面
+
+NodeWarden 现在已经有完整的主密码注册、主密码登录、刷新 token、2FA、设备记录、官方客户端兼容的 `UserDecryptionOptions`，也支持 vault item 里的 `login.fido2Credentials` 字段。但它还没有“账户 passkey 登录”。现有 `src/utils/passkey.ts` 只有 base64url、challenge、clientData 解析这类工具函数，不能完成 FIDO2/WebAuthn 服务端注册和认证验证。
+
+要支持“自己的 web 用 passkey 登录”和“官方/自定义浏览器扩展也能 passkey 登录”，不能只加一个登录按钮。必须补齐四块：
+
+1. Server 端新增账户 WebAuthn credential 表、challenge/token 防重放机制、FIDO2 attestation/assertion 验证、`grant_type=webauthn`。
+2. Server 响应里按 Bitwarden 形状返回 PRF 解密材料：登录 token 响应用单个 `UserDecryptionOptions.WebAuthnPrfOption`，sync 响应用多个 `UserDecryption.WebAuthnPrfOptions`。
+3. NodeWarden web 新增 passkey 注册、管理、登录和 PRF 解锁 vault key 的客户端流程。
+4. 扩展兼容要跟官方 Bitwarden endpoint 和 response shape 对齐。官方 browser extension 当前只在 Chromium 系浏览器开放 passkey 登录，因为 Firefox/Safari 扩展环境还不能按官方代码需要的方式覆盖 RP ID。
+
+下面按代码链路展开。
+
+## 术语边界
+
+这里有三个容易混淆的东西，文档后面严格区分：
+
+- 账户 passkey 登录：用户不用主密码，使用 WebAuthn/passkey 完成账号认证，并且用 PRF 解开 vault user key。官方 Bitwarden 叫 `WebAuthnLogin`。
+- Vault item 里的 passkey：某个登录条目保存网站 passkey/FIDO2 credential 数据，对应 NodeWarden 的 `cipher.login.fido2Credentials`。这是“保险库保存别的网站 passkey”，不是“登录 NodeWarden 账号”。
+- WebAuthn 2FA：主密码登录之后用安全密钥做第二因素。官方旧 web repo 里主要是这一类，不等于 passkey 登录。
+
+## NodeWarden 现状
+
+### 路由和入口
+
+NodeWarden 后端是 Cloudflare Workers + D1。主入口 `src/index.ts` 初始化存储后进入 router。认证边界在：
+
+- `src/router-public.ts`：公开接口，包含 `/identity/connect/token`、`/identity/accounts/prelogin`、`/api/accounts/register`。
+- `src/router-authenticated.ts`：需要 access token 的接口，包含 profile、change password、TOTP、sync、vault、devices。
+- `src/handlers/identity.ts`：OAuth/token 兼容入口。
+- `src/handlers/accounts.ts`：注册、profile、密码变更、TOTP、API key 等账户接口。
+
+目前公开路由没有：
+
+- `GET /identity/accounts/webauthn/assertion-options`
+- `POST /identity/connect/token` 的 `grant_type=webauthn`
+- `POST /api/webauthn/attestation-options`
+- `POST /api/webauthn/assertion-options`
+- `GET/POST/PUT /api/webauthn`
+
+### 注册链路
+
+NodeWarden 自己 web 的注册入口在 `webapp/src/lib/api/auth.ts` 的 `registerAccount()`：
+
+- 使用邮箱作为 salt，用 PBKDF2 派生 master key。
+- 再用 PBKDF2(masterKey, password, 1) 得到 client master password hash。
+- 随机生成 64 字节 vault symmetric key。
+- 用 masterKey 经 HKDF 拆成 enc/mac，把 vault key 加密成 Bitwarden `Key`。
+- 生成 RSA-OAEP key pair，把 private key 用 vault symmetric key 加密。
+- POST `/api/accounts/register`，提交 `email`、`name`、`masterPasswordHash`、`key`、KDF 参数、invite code、`keys.publicKey`、`keys.encryptedPrivateKey`。
+
+后端 `src/handlers/accounts.ts` 的 `handleRegister()`：
+
+- 第一个用户自动成为 admin，后续用户需要 invite。
+- 校验 `JWT_SECRET`、邮箱、KDF 下限、加密字符串形状、公钥/私钥。
+- 不直接保存 client hash，而是 `AuthService.hashPasswordServer(masterPasswordHash, email)` 后保存到 `users.master_password_hash`。
+- 保存 `users.key`、`users.private_key`、`users.public_key`、KDF 参数、`security_stamp`。
+
+结论：账户 passkey 注册不是替代账号注册，而是“用户已登录后在安全设置里新增一个可登录 credential”。仍然需要已有 vault user key 来生成 PRF keyset。
+
+### 主密码登录链路
+
+NodeWarden 自己 web 的登录入口是 `webapp/src/lib/app-auth.ts` 的 `performPasswordLogin()`：
+
+- 先 `deriveLoginHashLocally()` 得到 masterKey 和 client hash。
+- 调 `loginWithPassword()` POST `/identity/connect/token`。
+- token 成功后 `completeLogin()` 用 `token.Key` 和本地 masterKey 解开 vault key。
+- 保存离线解锁记录。
+
+`webapp/src/lib/api/auth.ts` 也有 `deriveLoginHash()` 和 `getPreloginKdfConfig()` 会调用 `/identity/accounts/prelogin`，但当前 `performPasswordLogin()` 走的是本地 fallback iterations。passkey 登录不应复用这条 masterKey 路径，因为 passkey 登录没有主密码，拿不到 password-derived masterKey。
+
+后端 `src/handlers/identity.ts` 的 `handleToken()` 当前支持：
+
+- `grant_type=password`
+- `grant_type=client_credentials`
+- `grant_type=refresh_token`
+
+密码登录成功后会：
+
+- 验证 IP 登录频率和用户状态。
+- `AuthService.verifyPassword()` 验证 client hash。
+- 处理 TOTP 或 remember 2FA token。
+- 记录/更新 device。
+- 生成 access token 和 refresh token。
+- 返回 `Key`、`PrivateKey`、`AccountKeys`、KDF 参数、`UserDecryptionOptions`。
+
+### UserDecryptionOptions 和 sync
+
+NodeWarden 的 `src/utils/user-decryption.ts` 当前只构造主密码解锁：
+
+- `HasMasterPassword: true`
+- `MasterPasswordUnlock`
+- `TrustedDeviceOption: null`
+- `KeyConnectorOption: null`
+
+`src/types/index.ts` 的 sync 类型里预留了 `UserDecryption.WebAuthnPrfOption?: null`，但当前 `src/handlers/sync.ts` 实际只返回 `MasterPasswordUnlock`，没有账户 passkey PRF 解密选项。
+
+passkey 登录必须新增两类 shape：
+
+- 登录 token 响应：`UserDecryptionOptions.WebAuthnPrfOption`，只返回本次认证所用 credential 的 PRF 解密材料。
+- sync 响应：`UserDecryption.WebAuthnPrfOptions`，返回该用户所有已启用 PRF keyset 的 passkey 解密材料，供官方客户端锁定/解锁和 key rotation 使用。
+
+### 现有 passkey 相关代码
+
+NodeWarden 已支持 vault item 里的 FIDO2/passkey 字段：
+
+- `src/types/index.ts`：`CipherLogin.fido2Credentials`
+- `src/handlers/ciphers.ts`：读写 cipher 时保留/规范化 `fido2Credentials`
+- `webapp/src/lib/api/vault.ts`：加密/解密 vault item 内的 `fido2Credentials`
+- `webapp/src/lib/types.ts`：`CipherLoginPasskey`
+
+这部分是“保存网站 passkey”，不是账户登录。
+
+`src/utils/passkey.ts` 只有：
+
+- `bytesToBase64Url()`
+- `base64UrlToBytes()`
+- `randomChallenge()`
+- `parseClientDataJSON()`
+
+缺少的核心能力：
+
+- attestation verification
+- assertion verification
+- authenticator public key 格式处理
+- signature verification
+- sign counter 更新
+- userHandle 与 user id 绑定验证
+- origin/RP ID 验证
+- challenge 过期和防重放
+
+### 数据库和备份影响
+
+NodeWarden schema 在这些地方需要同步：
+
+- `migrations/0001_init.sql`
+- `src/services/storage-schema.ts`
+- `wrangler.toml` migrations
+- `src/services/backup-archive.ts`
+- `src/services/backup-import.ts`
+- `shared/backup-schema` 相关类型
+
+当前表里没有账户 passkey credential，也没有 WebAuthn challenge 表。`devices` 表保存设备 trust/key 信息，不适合混入 passkey credential，因为 WebAuthn credential 需要自己的 public key、credential id、counter、AAGUID、PRF keyset 等字段。
+
+## 官方 Bitwarden server 参考
+
+上游代码位置：
+
+- `.codex-upstream/bitwarden-server`
+- 研究时 HEAD：`574f3fd`
+
+官方 server 里也有两个 WebAuthn 概念：
+
+- 传统 WebAuthn 2FA：`TwoFactorController`、`WebAuthnTokenProvider`
+- 账户 passkey 登录：`WebAuthnLogin`
+
+本项目要参考的是后者。
+
+### 公开 passkey 登录入口
+
+`src/Identity/Controllers/AccountsController.cs`
+
+- `GET /accounts/webauthn/assertion-options`
+- 返回 `WebAuthnLoginAssertionOptionsResponseModel`
+- response 包含：
+  - `options`
+  - `token`
+- token 使用 `WebAuthnLoginAssertionOptionsTokenable`
+- scope 为 `Authentication`
+- token 生命周期约 17 分钟
+
+`src/Identity/IdentityServer/RequestValidators/WebAuthnGrantValidator.cs`
+
+- 新增 OAuth extension grant：`grant_type=webauthn`
+- 从 form 读取：
+  - `token`
+  - `deviceResponse`
+- 解开 token，校验 scope 必须是 `Authentication`
+- 反序列化 `AuthenticatorAssertionRawResponse`
+- 调用 `AssertWebAuthnLoginCredential`
+- 把成功认证的 credential 传给 `UserDecryptionOptionsBuilder.WithWebAuthnLoginCredential(credential)`
+- 之后走通用登录成功逻辑，返回 access/refresh token 和账号加密状态。
+
+`src/Identity/IdentityServer/ApiClient.cs`
+
+- official identity client 的 allowed grant types 包含 `WebAuthnGrantValidator.GrantType`。
+
+`TwoFactorAuthenticationValidator` 里有一个重要行为：FIDO2 user verification 已经被视为第二因素，所以 passkey 登录成功后官方不会再要求额外 2FA。NodeWarden 之后需要明确策略：要兼容官方客户端，应把 passkey 登录视作已满足 2FA，否则官方 `LoginViaWebAuthnComponent` 会显示“不支持 passkey 2FA”的错误。
+
+### 账户 passkey 管理接口
+
+`src/Api/Auth/Controllers/WebAuthnController.cs`
+
+官方 authenticated API：
+
+- `GET /webauthn`：列出账户 passkey credentials。
+- `POST /webauthn/attestation-options`：主密码/secret verification 后生成 credential create options 和 token。
+- `POST /webauthn/assertion-options`：主密码/secret verification 后生成 assertion options 和 token，用于给已有 credential 启用/更新 PRF keyset。
+- `POST /webauthn`：保存新 credential。
+- `PUT /webauthn`：更新 credential 的 PRF encryption keyset。
+- `POST /webauthn/{id}/delete`：删除 credential。
+
+官方创建 credential 时保存：
+
+- `name`
+- `token`
+- `deviceResponse`
+- `supportsPrf`
+- 可选 `encryptedUserKey`
+- 可选 `encryptedPublicKey`
+- 可选 `encryptedPrivateKey`
+
+官方最多允许 5 个账户 passkey credentials。
+
+### 官方 WebAuthnCredential 表
+
+`src/Core/Auth/Entities/WebAuthnCredential.cs`
+
+字段：
+
+- `Id`
+- `UserId`
+- `Name`
+- `PublicKey`
+- `CredentialId`
+- `Counter`
+- `Type`
+- `AaGuid`
+- `EncryptedUserKey`
+- `EncryptedPrivateKey`
+- `EncryptedPublicKey`
+- `SupportsPrf`
+- `CreationDate`
+- `RevisionDate`
+
+SQLite migration：`util/SqliteMigrations/Migrations/20231213032045_WebAuthnLoginCredentials.cs`
+
+表名是 `WebAuthnCredential`，对 `User` 做 cascade delete，并按 `UserId` 建索引。
+
+`GetPrfStatus()`：
+
+- `Unsupported`：`SupportsPrf` 为 false。
+- `Supported`：credential 支持 PRF，但还没有完整 encrypted keyset。
+- `Enabled`：`EncryptedUserKey`、`EncryptedPrivateKey`、`EncryptedPublicKey` 都存在。
+
+### 官方创建和认证策略
+
+`GetWebAuthnLoginCredentialCreateOptionsCommand.cs`
+
+- 使用 Fido2NetLib。
+- `user.id` 是用户 id bytes。
+- `user.name/displayName` 使用用户邮箱。
+- 排除当前用户已有 credential ids。
+- `residentKey: required`
+- `userVerification: required`
+- `attestation: none`
+
+`GetWebAuthnLoginCredentialAssertionOptionsCommand.cs`
+
+- `allowCredentials` 传空数组。
+- `userVerification: required`
+- 空 allow list 代表使用 discoverable credentials，也就是 passkey 登录页可以不先输入邮箱。
+
+`CreateWebAuthnLoginCredentialCommand.cs`
+
+- 限制每用户最多 5 个。
+- 检查 credential id 在该用户下不能重复。
+- FIDO `MakeNewCredentialAsync` 验证 attestation。
+- 保存 credential id/public key/counter/type/AAGUID/PRF keyset。
+
+`AssertWebAuthnLoginCredentialCommand.cs`
+
+- 先用 challenge cache 防重放。
+- 从 assertion response 的 `userHandle` 解析出 user id。
+- 加载该用户所有 WebAuthn credentials。
+- 用 credential id 找到记录。
+- FIDO `MakeAssertionAsync` 验证签名、challenge、origin、RP ID、user verification。
+- 成功后更新 counter。
+
+### 官方 PRF 解密协议
+
+`src/Core/Auth/Models/Api/Response/UserDecryptionOptions.cs`
+
+`WebAuthnPrfDecryptionOption` 字段：
+
+- `EncryptedPrivateKey`
+- `EncryptedUserKey`
+- `CredentialId`
+- `Transports`
+
+`src/Identity/IdentityServer/UserDecryptionOptionsBuilder.cs`
+
+- `WithWebAuthnLoginCredential()` 只在 credential 的 PRF status 是 `Enabled` 时加入 `WebAuthnPrfOption`。
+- 如果 credential 没有 PRF keyset，passkey 只能认证账号，不能解开 vault。
+
+`src/Api/Vault/Models/Response/SyncResponseModel.cs`
+
+- sync response 会把所有 enabled PRF credentials 放进 `UserDecryption.WebAuthnPrfOptions`。
+
+## 官方 Bitwarden web/browser client 参考
+
+上游代码位置：
+
+- `.codex-upstream/bitwarden-clients`
+- `.codex-upstream/bitwarden-browser`
+- 两者研究时 HEAD 都是 `825f9be`，browser repo 内容和 clients monorepo 对应。
+
+旧的 `.codex-upstream/bitwarden-web` 主要有 WebAuthn connector 和 2FA 设置页，没有现代账户 passkey 登录主流程。账户 passkey 登录应以 `bitwarden-clients` 为准。
+
+### 登录按钮可见性
+
+`libs/auth/src/angular/login/default-login-component.service.ts`
+
+- 默认只对 `ClientType.Web` 开启 passkey 登录。
+
+`apps/browser/src/auth/popup/login/extension-login-component.service.ts`
+
+- browser extension 覆盖逻辑：只对 Chromium 开启。
+- 注释说明 Firefox 和 Safari 不能在扩展里覆盖 relying party ID。
+- 官方代码引用了 W3C webextensions issue 238、Mozilla bug 1956484、Apple forum thread 774351。
+
+结论：NodeWarden 后端即使完全兼容官方 passkey API，官方扩展也只有 Chromium 系会显示 passkey 登录入口。
+
+### Passkey 登录页
+
+`libs/angular/src/auth/login-via-webauthn/login-via-webauthn.component.ts`
+
+流程：
+
+1. 进入 `/login-with-passkey` 后自动开始认证。
+2. 调 `webAuthnLoginService.getCredentialAssertionOptions()`。
+3. 调 `webAuthnLoginService.assertCredential(options)` 触发 `navigator.credentials.get()`。
+4. 调 `webAuthnLoginService.logIn(assertion)` 走 identity token grant。
+5. 如果 `authResult.requiresTwoFactor` 为 true，显示“客户端不支持 passkey 2FA”错误。
+6. 只有本地 `keyService.userKey$(authResult.userId)` 已经拿到 user key，才运行 login success handler。
+7. 成功路由：
+   - Web：`/vault`
+   - Browser：`/tabs/vault`
+   - Desktop：`/vault`
+
+Browser popout 下还会在成功后重新打开普通 popup 并关闭 popout。
+
+### 客户端 passkey 登录请求
+
+`libs/common/src/auth/services/webauthn-login/webauthn-login-api.service.ts`
+
+- GET `${identityUrl}/accounts/webauthn/assertion-options`
+- 如果 NodeWarden 的 identityUrl 是站点 origin + `/identity`，实际路径就是 `/identity/accounts/webauthn/assertion-options`。
+
+`libs/common/src/auth/services/webauthn-login/webauthn-login.service.ts`
+
+- `navigator.credentials.get({ publicKey: options })`
+- 会主动加 PRF extension：
+  - salt 是 `SHA-256("passwordless-login")`
+  - extension shape 是 `extensions.prf.eval.first`
+- 从 `credential.getClientExtensionResults().prf.results.first` 取 PRF 输出。
+- 用 `WebAuthnLoginPrfKeyService.createSymmetricKeyFromPrf()` 转成 PRF key。
+- 构造 `WebAuthnLoginAssertionResponseRequest`。
+- 明确检查 `deviceResponse.extensions` 里不能含 `prf`，避免把 PRF 输出泄漏给服务端。
+
+`libs/common/src/auth/services/webauthn-login/webauthn-login-prf-key.service.ts`
+
+- salt 常量：`passwordless-login`
+- 先 SHA-256。
+- 再用 HKDF expand 拆成 64 字节：
+  - `"enc"` 32 bytes
+  - `"mac"` 32 bytes
+
+`libs/common/src/auth/models/request/identity-token/webauthn-login-token.request.ts`
+
+form encoded token 请求字段：
+
+- `grant_type=webauthn`
+- `token=<server assertion options token>`
+- `deviceResponse=<JSON string>`
+- 还会带 common device request 字段。
+
+`libs/common/src/auth/services/webauthn-login/request/webauthn-login-assertion-response.request.ts`
+
+`deviceResponse` shape：
+
+- `id`
+- `rawId`
+- `type`
+- `extensions: {}`
+- `response.authenticatorData`
+- `response.signature`
+- `response.clientDataJSON`
+- `response.userHandle`
+
+全部二进制字段使用 base64url。
+
+### 客户端如何用 PRF 解 vault key
+
+`libs/auth/src/common/login-strategies/webauthn-login.strategy.ts`
+
+- `setMasterKey()` 是空实现，因为 passkey 登录没有主密码 masterKey。
+- `setUserKey()`：
+  - 如果 token response 有 `key`，保存为 master-key-encrypted user key，兼容主密码解锁。
+  - 如果 `userDecryptionOptions.webAuthnPrfOption` 存在，且本地 assertion 得到了 `prfKey`：
+    1. 用 PRF key unwrap `encryptedPrivateKey`。
+    2. 用 private key decapsulate `encryptedUserKey`。
+    3. 得到 user key，写入 `keyService`。
+
+核心约束：服务端永远看不到 PRF 输出。服务端只保存和返回被 PRF 相关密钥加密后的 keyset。
+
+### 官方 web 设置页注册 passkey
+
+`apps/web/src/app/auth/core/services/webauthn-login/webauthn-login-admin-api.service.ts`
+
+调用的 API：
+
+- `POST /webauthn/attestation-options`
+- `POST /webauthn/assertion-options`
+- `POST /webauthn`
+- `GET /webauthn`
+- `POST /webauthn/{id}/delete`
+- `PUT /webauthn`
+
+`apps/web/src/app/auth/core/services/webauthn-login/webauthn-login-admin.service.ts`
+
+创建流程：
+
+1. 用户做 secret verification。
+2. 请求 attestation options。
+3. `navigator.credentials.create({ publicKey: options })`，并带 `extensions.prf = {}`。
+4. 从 client extension results 判断 `supportsPrf`。
+5. 如果要用于 vault encryption，再立即做一次 `navigator.credentials.get()`：
+   - `allowCredentials` 锁定刚创建的 credential。
+   - 使用同一个 challenge、rpId、timeout、userVerification。
+   - 带 PRF eval salt。
+6. 用 PRF key 和当前 user key 创建 rotateable keyset。
+7. 保存 credential，带上 `encryptedUserKey`、`encryptedPublicKey`、`encryptedPrivateKey`。
+
+删除流程需要 secret verification。启用 encryption 的流程是对已有 credential 做 assertion，再创建并 PUT keyset。
+
+`apps/web/src/app/auth/core/enums/webauthn-login-credential-prf-status.enum.ts`
+
+- `Enabled = 0`
+- `Supported = 1`
+- `Unsupported = 2`
+
+## NodeWarden 应实现的协议形状
+
+### 公开登录流程
+
+目标兼容官方客户端和 NodeWarden 自己 web：
+
+1. `GET /identity/accounts/webauthn/assertion-options`
+   - 生成 discoverable credential assertion options。
+   - `allowCredentials: []`
+   - `userVerification: "required"`
+   - 返回 `{ options, token }`。
+   - token 绑定 challenge、scope=`Authentication`、RP ID、origin/audience、过期时间。
+
+2. Browser/web 调 `navigator.credentials.get()`。
+   - NodeWarden 自己 web 也要使用 PRF extension。
+   - PRF salt 必须和官方一致：`SHA-256("passwordless-login")`。
+
+3. `POST /identity/connect/token`
+   - 支持 `grant_type=webauthn`。
+   - 接收 `token`、`deviceResponse`、device fields。
+   - 解 token，校验 challenge/scope/过期。
+   - 验证 assertion。
+   - 从 `userHandle` 找到 user id。
+   - 从 credential id 找到 passkey record。
+   - 更新 counter。
+   - 记录/更新 device。
+   - 返回 access/refresh token、`AccountKeys`、`UserDecryptionOptions.WebAuthnPrfOption`。
+
+如果用户启用了 TOTP，建议为了官方兼容先遵循 Bitwarden：passkey 的 user verification 视作已满足第二因素。否则官方 passkey 登录页会进入 unsupported 2FA 错误状态。
+
+### 账户 passkey 管理流程
+
+建议对齐官方 API，同时在 NodeWarden 内部可挂到 `/api/webauthn`：
+
+- `GET /api/webauthn`
+- `POST /api/webauthn/attestation-options`
+- `POST /api/webauthn/assertion-options`
+- `POST /api/webauthn`
+- `PUT /api/webauthn`
+- `POST /api/webauthn/:id/delete`
+
+为了官方客户端兼容，可能还需要接受无 `/api` 前缀的 aliases：
+
+- `/webauthn`
+- `/webauthn/attestation-options`
+- `/webauthn/assertion-options`
+- `/webauthn/:id/delete`
+
+NodeWarden 自己 web 可以直接用 `/api/webauthn`，官方 web/browser 客户端会按它自己的 API base 组装 `/webauthn`。
+
+### 建议新增表
+
+按 NodeWarden 命名风格，建议用小写 snake_case：
+
+```sql
+CREATE TABLE IF NOT EXISTS webauthn_credentials (
+  id TEXT PRIMARY KEY,
+  user_id TEXT NOT NULL,
+  name TEXT NOT NULL,
+  public_key TEXT NOT NULL,
+  credential_id TEXT NOT NULL,
+  counter INTEGER NOT NULL DEFAULT 0,
+  type TEXT,
+  aa_guid TEXT,
+  transports TEXT,
+  encrypted_user_key TEXT,
+  encrypted_public_key TEXT,
+  encrypted_private_key TEXT,
+  supports_prf INTEGER NOT NULL DEFAULT 0,
+  created_at TEXT NOT NULL,
+  updated_at TEXT NOT NULL,
+  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+);
+
+CREATE UNIQUE INDEX IF NOT EXISTS idx_webauthn_credentials_user_credential
+  ON webauthn_credentials(user_id, credential_id);
+
+CREATE INDEX IF NOT EXISTS idx_webauthn_credentials_user
+  ON webauthn_credentials(user_id);
+```
+
+如果要更严格防止同一个 credential id 被跨用户重复注册，也可以加全局 unique index `credential_id`。官方代码至少检查同用户唯一；实际安全上更建议全局唯一，因为 credential id 本身应该唯一标识 authenticator credential。
+
+PRF status 不必落库为枚举，可以由字段计算：
+
+- `supports_prf = 0` => `Unsupported`
+- `supports_prf = 1` 且三段 encrypted key 不全 => `Supported`
+- `supports_prf = 1` 且三段 encrypted key 全存在 => `Enabled`
+
+### Challenge/token 存储
+
+官方 server 用 protected token 携带 options，再用 challenge cache 防重放。NodeWarden 在 Workers/D1 里建议组合：
+
+- token：HMAC/JWT 样式，绑定 `scope`、`challenge`、`userId?`、`rpId`、`createdAt`、`expiresAt`。
+- D1 表或 KV：记录 challenge 是否使用过，至少字段 `challenge_hash`、`scope`、`user_id`、`expires_at`、`used_at`。
+- 登录 assertion options 是公开接口，不绑定 user id；create/update/delete 管理流程应绑定 user id。
+- 验证成功后立即 mark used。
+
+建议 scopes：
+
+- `Authentication`
+- `CreateCredential`
+- `UpdateKeySet`
+
+官方还有 `PrfRegistration` 语义，NodeWarden 可以用 `CreateCredential` 覆盖，只要 token 逻辑严谨即可。
+
+### 服务端 WebAuthn 验证库
+
+NodeWarden 当前没有 FIDO2/WebAuthn 服务端验证依赖。不要手写签名和 attestation 解析。
+
+候选：`@simplewebauthn/server`。官方文档当前说明它提供 `generateRegistrationOptions`、`verifyRegistrationResponse`、`generateAuthenticationOptions`、`verifyAuthenticationResponse`，并记录了 RP ID、origin、credential public key、counter、transports 等数据结构。文档地址：https://simplewebauthn.dev/docs/packages/server
+
+注意：NodeWarden 跑在 Cloudflare Workers，不是普通 Node server。正式选库前需要做一次构建/runtime 验证，确认包不会依赖 Workers 不支持的 Node API。这个验证属于实现阶段，不在本研究文档里写测试程序。
+
+## NodeWarden web 需要改的地方
+
+### 登录页
+
+当前登录 UI 在 `webapp/src/components/AuthViews.tsx`，状态和行为主要由 `webapp/src/App.tsx`、`webapp/src/lib/app-auth.ts` 管。
+
+新增：
+
+- 登录页增加“使用 passkey 登录”按钮。
+- 新增 `performPasskeyLogin()`：
+  1. GET `/identity/accounts/webauthn/assertion-options`
+  2. 转换 server options 里的 base64url challenge/user id/credential id 为 ArrayBuffer。
+  3. `navigator.credentials.get()`，带 PRF salt。
+  4. POST `/identity/connect/token`，`grant_type=webauthn`。
+  5. 从 response 的 `UserDecryptionOptions.WebAuthnPrfOption` 取 encrypted keyset。
+  6. 用本地 PRF key 解出 user key。
+  7. 构造 `SessionState` 并进入 app。
+
+不能复用 `completeLogin(token, email, masterKey, fallbackKdfIterations)`，因为它要求 masterKey。应新增 passkey 专用 complete 函数。
+
+### 设置页
+
+当前账户/安全相关 UI 在 `webapp/src/components/SettingsPage.tsx` 一带。
+
+新增：
+
+- Passkey 列表。
+- 新建 passkey dialog。
+- 删除 passkey。
+- 对支持 PRF 但未启用 encryption 的 passkey，提供“启用用于登录解锁”的操作。
+
+自己 web 的新建流程要和官方一致：
+
+1. 已登录状态下先验证主密码或现有 session secret。
+2. 请求 attestation options。
+3. `navigator.credentials.create()` 带 `extensions.prf = {}`。
+4. 如果用户希望这个 passkey 可直接解锁 vault，再对刚创建 credential 做一次 `navigator.credentials.get()` 获取 PRF 输出。
+5. 用 PRF key 加密/封装当前 user key，发送到 server 保存。
+
+### 客户端加密能力
+
+NodeWarden web 当前已经有：
+
+- PBKDF2
+- HKDF expand
+- Bitwarden EncString 加解密
+- RSA-OAEP private key 加密
+
+但 passkey PRF keyset 需要和官方策略对齐：
+
+- PRF key 是 64 字节 symmetric key，前 32 enc、后 32 mac。
+- `encryptedPrivateKey` 用 PRF key wrap 一个 decapsulation private key。
+- `encryptedUserKey` 用对应 public key encapsulate user key。
+- `encryptedPublicKey` 用于 key rotation。
+
+这里需要认真复用或补齐 NodeWarden 现有 crypto helper，避免做出和官方客户端无法互解的 keyset。
+
+## 扩展兼容要求
+
+### 官方 browser extension
+
+官方 extension passkey 登录入口在：
+
+- `apps/browser/src/auth/popup/login/extension-login-component.service.ts`
+- 只在 Chromium 开启。
+
+如果要官方/派生扩展能对 NodeWarden passkey 登录：
+
+- identity URL 必须能访问 `/accounts/webauthn/assertion-options`。
+- token URL 必须支持 `grant_type=webauthn`。
+- API URL 必须能访问 `/webauthn` 管理接口。
+- response 大小写和字段名要同时照顾 PascalCase/camelCase，NodeWarden 当前 token response 已经在一些字段上双写，这个风格应继续沿用。
+- passkey 登录成功时必须返回可解开 vault 的 `webAuthnPrfOption`，否则官方组件虽然认证成功，也不会进入可用 vault。
+
+### RP ID 和 origin
+
+自己的 web：
+
+- RP ID 通常是站点 host，例如 `vault.example.com`。
+- origin 是 `https://vault.example.com`。
+
+官方 browser extension：
+
+- 扩展页面 origin 是 `chrome-extension://...`。
+- 官方之所以只开 Chromium，是因为 Chromium extension 具备它需要的 RP ID 覆盖能力。
+- NodeWarden server 验证 assertion 时必须允许正确的 origin/RP ID 组合。这里不能简单只接受当前 request origin，否则扩展登录会失败。
+
+建议配置化：
+
+- `WEBAUTHN_RP_ID`
+- `WEBAUTHN_RP_NAME`
+- `WEBAUTHN_ALLOWED_ORIGINS`
+
+默认可以从 request URL 推导 web origin，但生产建议显式配置。
+
+## 安全约束
+
+- 所有账户 passkey 必须 `userVerification: required`。
+- 登录 assertion 使用 discoverable credential，`userHandle` 必须能解析成 user id 并和 credential 记录一致。
+- challenge 必须有过期时间和一次性使用标记。
+- PRF 输出绝不能传给 server，也不能写入日志。
+- token 里要绑定 scope，防止 attestation token 被拿去 authentication 用。
+- counter 要更新。遇到 counter 异常时至少记录 audit event，是否阻断要结合 multi-device passkey 现实处理。
+- 每用户 credential 数量限制建议沿用官方 5 个。
+- 删除/新增/启用 encryption 必须要求已登录用户二次验证。
+- 密码变更、user key rotation 后，所有 enabled PRF credentials 的 keyset 也要 rotation，否则 passkey 登录会解不开新 vault key。
+- 备份导出/导入必须包含账户 passkey 表，否则恢复后 passkey 登录会全部失效。
+- 审计日志建议新增：
+  - `auth.passkey.login.success`
+  - `auth.passkey.login.failed`
+  - `account.passkey.create`
+  - `account.passkey.delete`
+  - `account.passkey.encryption.enable`
+  - `account.passkey.rotate`
+
+## 建议实施顺序
+
+### 第一阶段：后端基础
+
+1. 新增 `webauthn_credentials` 和 challenge 表。
+2. 新增 storage repo。
+3. 接入 WebAuthn 服务端验证库。
+4. 实现 assertion options 和 `grant_type=webauthn`。
+5. token response 加 `WebAuthnPrfOption` shape。
+
+这阶段先能让“已有手工塞入的 enabled credential”完成登录验证，但还不做 UI。
+
+### 第二阶段：账户 passkey 管理 API
+
+1. 实现 `/api/webauthn` 和 `/webauthn` aliases。
+2. 实现 attestation options、save credential、list、delete、enable/update encryption。
+3. 加 audit event。
+4. 接入 backup export/import。
+5. sync response 加 `WebAuthnPrfOptions`。
+
+### 第三阶段：NodeWarden 自己 web
+
+1. 登录页 passkey 按钮和 `performPasskeyLogin()`。
+2. Passkey 设置页。
+3. PRF keyset 创建、保存、删除、启用 encryption。
+4. 浏览器能力判断和错误提示。
+
+### 第四阶段：扩展兼容
+
+1. 用官方 browser extension 的 Chromium passkey 登录流程校对 endpoint。
+2. 校对 `/config` 里 identity/api/web vault URL。
+3. 校对 RP ID、allowed origins。
+4. 必要时加兼容字段或 alias route。
+
+按用户要求，本阶段只需要代码跑通不报错；不在这里写可视化测试或测试程序。
