# Register Devices at Scale

Once you understand the possibilities, you can choose the procedure that is right for you.

## Connect Device Registration Algorithm

By design, [JFrog Connect](#connect-device-registration-algorithm) is able to register new devices by duplicating an image that has the Connect Agent installed inside it. When a new device is connected to the Internet, the device registration algorithm is initiated. The algorithm recognizes new devices if they do not have a device token yet. The device token is then generated and saved encrypted in the `settings.json` file.

Therefore, a method for registering devices at scale must include:

* Obtaining the Connect Agent, for example, one of the following: 
  * Register a single device from the web UI 
  * Obtain the Connect Agent binary from JFrog Connect Support
* Creating an image for duplication, for example:
  * Freeze an image of a registered device
  * Build a Linux-based image that includes the Connect Agent binary

For the sake of simplicity, we describe two methods for registering large numbers of devices at a time that incorporate the above requirements. You can choose the method that is suitable for you.

## Freeze Image on Device

In this method, you register a single device and then take a freeze of the OS image to copy to other devices. This method is advantageous if you have a real device with internet connectivity and the OS of that device is exactly what you want on all other devices.

This procedure consists of the following major steps:

1. [Register a single device](https://docs.connect.jfrog.io/get-to-know-new-ui/get-started/register-device-agent-7.0).
2. Take a freeze of the OS image on the device.
3. Burn the image on SD cards or eMMC flashes.

For the detailed procedure, see [Freeze Image on Device](https://docs.connect.jfrog.io/features-new-ui/account-management/register-linux-devices-at-scale/freeze-image-on-device).

## Build Image with Agent

This method is suitable if you would like to build a custom image that includes the Connect Agent. For example, you may want to create an image that includes your off-the-shelf Linux-based OS, some software that will run on the device, and the Connect Agent. As another example, you want to build a completely customized Linux-based OS for your edge device and include the Connect Agent. You can create this image in a lab environment, i.e., on your PC, and an actual device is not required.

This procedure consists of the following major steps.

1. Get a copy of the Connect Agent on your PC. (To obtain a copy of the Connect Agent binary, contact JFrog Connect Support<mark style="color:purple;">.</mark>)
2. Copy the Connect Agent to your OS file system.
3. Burn the image on SD cards or eMMC flashes.
