+# Plan 28-01 Summary: Logto Management API Client & Account Routes
+
+## What Was Built
+
+1. **LogtoManagementClient** (`src/server/services/logto.service.ts`) — M2M token-based client for Logto Management API with automatic token caching and refresh. Methods: getUser, verifyPassword, updatePassword, hasPassword, updateEmail, deleteUser.
+
+2. **Account management routes** (`src/server/routes/account.ts`) — Four endpoints:
+   - `POST /api/account/password` — Change password (verifies current first)
+   - `POST /api/account/email` — Change email
+   - `GET /api/account/has-password` — Check if user has password
+   - `POST /api/account/delete` — Delete account with public setup anonymization
+
+3. **Zod schemas** added to `src/shared/schemas.ts`: changePasswordSchema, changeEmailSchema, deleteAccountSchema
+
+4. **12 unit tests** covering all LogtoManagementClient methods and token caching behavior
+

+- [x] All routes use requireAuth middleware (T-28-05)
+- [x] Deletion requires "DELETE" confirmation (T-28-04)
+- [x] Routes registered in index.ts
