How to generate ClientCredentials as devicecredentials

Hi,

To register the device using Device Registration Tool Provided in the SDK, Open the command prompt and go to the location of the deviceregistration.exe and then run with the following command. You can find this file in the CRM 2011 sdk i.e. sdk\tools\deviceregistration\bin\Debug

C:\>deviceregistration.exe /operation:Register

This will register you device and give Device Username and Device Password.

The CRM 2011 online supports only claim based authentication so the device username and the password is very important and a necessary component for generating the code{class} for using the Organization Service data and metadata.

Here is an excellent article on this.
