How to create meaningful device credentials using Device Registration Tool

To create a standalone application ( web application or console application) or generate early bind classes using CrmSvcUtil, we need a connection string to connect to the CRM. The connection strings are different for different deployment types. Here is the link to the MSDN article about CRM connection strings.
To connect to CRMOnline, we need to specify the device credentials as well as LIVE username and password. Here is an example of CRMOnline connection string.
Url=;; Password=passcode; DeviceID=contoso-ba9f6b7b2e6d; DevicePassword=passcode
The device credentials sit in “C:\Users\username\LiveDeviceID\LiveDeviceID.XML” file.
If the file does not exist then it means your device is not registered. If it does exist then the file contents will look like the following screen.
If you look at username and pwd in the above screen shot, they look like random letters and numbers.
Microsoft provides the “Device Registration Tool” to register the device for CRMOnline. This tool can be found at “\sdk\tools\deviceregistration\bin\Debug.DeviceRegisteration.exe” location.
The DeviceRegistration.exe supports 2 operations.
  • Show
  • Register
Here is some of the screen shots of “Device Registration Tool” in action.
The second screen shot displays the outcome of register operation. The tool created a device id and device password. As I mentioned earlier in the blog, these credentials are not readable and you can’t really remember them. But we can actually specify the device id and password by passing username and password parameter in the register operation. Have a look at the following screen.
That's how you can specify your own device id and device password for device registration. The only thing I can’t work it out is that registration tool adds 11 in front of the specified device id.
