# Managing Devices from the Admin Panel

{/* category: Check-In Devices */}

The **Check-In Devices** section in the admin panel gives you full visibility into all registered devices across your facility — and the ability to deactivate or permanently remove them.

## The Device List

Each row in the device list shows:

| Column                | Description                                                                                             |
| --------------------- | ------------------------------------------------------------------------------------------------------- |
| **Status dot**        | **Green** = online (seen within the last 5 minutes); **Gray** = offline or stale; **Red** = deactivated |
| **Device name**       | The label assigned during setup (e.g. "Main Entrance Tablet")                                           |
| **Location**          | The location tag set on the device                                                                      |
| **Guard name**        | The operator name assigned to this device                                                               |
| **Last seen**         | How long ago the device last sent a heartbeat ("just now", "5m ago", "2h ago")                          |
| **Deactivated badge** | A red pill shown only when the device has been deactivated by an admin                                  |

## Device Actions

Click the **three-dot menu (⋮)** on any device row to access:

### Deactivate

Temporarily prevents the device from scanning. The device receives the deactivation signal on its next heartbeat (within 2 minutes) and is immediately locked with a **Revoked** lock screen. The operator cannot bypass this — they must sign out.

* The device record is retained; no data is lost
* You can **reactivate** the device at any time
* **Use this when:** a device is lost, stolen, or temporarily taken out of service

### Reactivate

Re-enables a previously deactivated device. The device will resume scanning normally on its next heartbeat. The operator may need to tap **Reconnect** on the lock screen.

### Revoke

Permanently removes the device from your organization. The device is deleted from the system — it cannot be reactivated and must be re-registered from scratch if needed again.

* A confirmation dialog is shown before deletion
* All scan logs from the device remain in your **Scan Logs** history
* **Use this when:** a device is permanently decommissioned, replaced, or the app has been reinstalled

## Registering a New Device

The top of the Check-In Devices page contains the registration tools:

* **Generate Code** — creates a 6-character one-time code (valid for 15 minutes) that the operator enters during device setup
* **Send Setup Email** — emails a no-expiry registration code and setup instructions to an operator

See the Registering a New Device article for a step-by-step walkthrough.

## Monitoring Device Health

The `last seen` timestamp tells you whether each device is actively sending heartbeats:

* **"Just now"** or **"Xm ago" (\< 5 min)** — device is online and operational
* **"Xm ago" (5+ min)** — device may have lost connectivity; check the location
* **"Xh ago"** or a date — device has been offline for an extended period; investigate

A device that has been offline for its configured maximum duration (default 24 hours) will show a lock screen to its operator and require a reconnection before scans can resume.
