+# View and Manage Logged-in Devices
+
+**ID:** EU-003
+**Priority:** Medium
+**Status:** Planned
+
+## User Story
+As an end user, I want to view all devices where I'm logged in and remotely log out of specific devices so that I can maintain control over my account security.
+
+## Acceptance Criteria
+- [ ] User can view a list of all active sessions/devices
+- [ ] Each device entry shows: device type, browser, location (approximate), last activity
+- [ ] User can name/label devices for easy identification
+- [ ] User can log out of any individual device remotely
+- [ ] User can log out of all devices except the current one
+- [ ] User receives notification when a new device logs in
+
+## Technical Notes
+- Device ID tracking infrastructure exists but is blocked by JWT handling issues
+- Need to complete `attachDeviceId` handler (currently returns `ok: false`)
+- Store device fingerprint, user agent, IP-based geolocation
+- Integrate with multi-refresh-token system (EU-001)
+
