**Devices** lists the computers that use Surepass in your labs. Open **Computer Lab → Devices**.

## How computers are registered

With **Device Auto-Registration** on, a computer is registered by itself the first time it opens the Surepass sign-in page on your network. With it off, only computers already registered can use the sign-in page.

**Auto-Registration Settings** (schools):

- **Device Code Prefix**: new computers are coded PC-001, PC-002 and so on.
- **Default Location Label**: such as "Computer Lab".
- **Allowed IP Ranges**: only computers in these network ranges are registered. With none, every computer on the network is registered. Ask your IT staff before changing this.

## The device list

Shows each device's name, **Code**, address, **Assigned Seat**, **Last Seen** and **Status**, with totals for active, assigned and unassigned devices.

- **Rename** a device. The name is for staff; the sign-in page shows only the computer code.
- **Edit Computer Code**: the ID shown on the sign-in page. It must be unique.
- **Bulk Allocate Codes**: give every device a new code in order, with a **Prefix**, **Start #** and number of **Digits**. Check the preview first.
- **Delete** a device. Unassign it from its seat first.

Link devices to seats in the lab layout, or with **Auto Arrange**. See [Laying out a lab room](https://helpcenter.academium.com.ng/academium-surepass/article/sp-laying-out-a-lab-room.md).
