Sample using Limited Input (device flow) authentication

This sample demonstrates the ARTIK cloud services Limited Input (device flow) authentication. This flow allows a user to use a secondary device (e.g. mobile phone) to complete authentication on a device with limited input (e.g. no keyboard). In this example, a console application will authenticate when the user authenticates remotely with a phone (or another computer) via the web.

Prerequisites

• Java version >= 1.7
• mvn (for installing dependencies)
• Eclipse (or your favorite editor)

Setup / Installation

You will first need to create an application by visiting https://developer.artik.cloud.

1. Add any permission scope or device types to the application (optional)
2. Set the authentication type to "Limited Input" (required)
3. Retrive the client_id which will be needed later (required)

If you need help with any of the above steps, read the application guide.

Code setup

1. We will use Eclipse to import project as a maven project: File->Import->Maven->Existing Maven Projects
2. Edit the /src/Config.java and enter your client_id you retrieved earlier.

class Config {	
	public static final String CLIENT_ID  = "your client id";
    //...
}    

Run sample

Run the DeviceFlowLimitedInput.java. Here are the steps using Eclipse IDE:

Right Click `DeviceFlowLimitedInput.java` from the editor
Run As -> Java Application

If running correctly, it will display a code for the user to enter at the link https://artik.cloud/go, and will wait until user has completed this step.
