+## v0.6.9 — Session Lifetime Config
+
+Admin-configurable session durations, "keep me logged in" opt-in, and
+optional idle timeout. Completes the auth hardening started in v0.6.8.
+
+### Added
+
+- **Admin session settings**: `session.access_token_ttl` (default 15m,
+  clamp 5m–60m) and `session.refresh_token_ttl` (default 7d, clamp
+  1h–90d) stored in `global_settings`. New `LoadSessionConfig()` helper
+  reads and clamps values with `parseDurationString()` supporting `m`,
+  `h`, `d` suffixes.
+- **"Keep me logged in" checkbox**: Login form opt-in. Checked = full
+  `refresh_token_ttl`. Unchecked = capped at 24h. Cookie `max-age`
+  tracks whichever lifetime was chosen. `keep_login` flag stored on
+  refresh token row.
+- **Config-driven token generation**: `generateTokens()` reads TTLs from
+  `global_settings` instead of hardcoded `15*time.Minute` /
+  `7*24*time.Hour`. Response includes `expires_in` and
+  `refresh_expires_in` (seconds) so the client schedules refresh
+  correctly.
+- **Idle timeout (optional)**: Admin-toggleable (default off). Server
+  checks `last_activity_at` on refresh-token row; rejects if gap exceeds
+  `session.idle_timeout`. Client SDK pings `POST /api/v1/auth/activity`
+  on click/keydown (debounced, max 1/min).
+- **Admin Settings > Session section**: Dropdowns for access TTL, refresh
+  TTL, and idle timeout with toggle.
+- **7 new tests**: Duration parsing, clamping (low/high), defaults,
+  invalid values, empty idle timeout.
+
+### Changed
+
+- `CreateRefreshToken` store method now accepts `keepLogin bool`
+  parameter; both Postgres and SQLite implementations updated.
+- `GetRefreshTokenInfo` returns `RefreshTokenInfo` struct with
+  `UserID`, `KeepLogin`, `LastActivityAt` for idle-timeout decisions.
+- SDK `auth.login()` accepts optional third `keepLogin` parameter;
+  cookie max-age derived from server `refresh_expires_in` response.
+- SDK boots activity tracking after successful auth boot.
+
+## v0.6.8 — Cookie Fix + UI Hardening Roadmap
+
+### Fixed
+
+- **Session cookie max-age bug**: `arm_token` cookie was set to 15 min
+  (matching access token) while refresh token lasted 7 days. Cookie now
+  matches refresh token lifetime so Go SSR middleware can serve page
+  shells while JS refreshes the access token client-side.
+
+### Added
+
+- **ROADMAP-UI.md**: Detailed UI hardening roadmap (v0.6.9–v0.6.15)
+  covering session config, viewport foundation, CSS deduplication,
+  extension CSS isolation, responsive layout, visual polish, and
+  automated usability survey gate.
+
 ## v0.6.7 — Native mTLS
 
 End-to-end mutual TLS without a reverse proxy. Targets systemd+podman
