To enable Live ID logon for your website, you must register it on the Windows Live application management site at the following address: https://manage.dev.live.com/.
1. Once on the page, sign in with your Windows Live ID (you may need to create an account if you don't already have one) and you will be redirected to the application registration page.
2. Here, enter an appropriate Application name that will be used to identify your website in the Windows Live user interface (click Create application if you already have an application registered and wish to add another one):
3. On the next screen, click on the Application Settings Page link and switch to the API Settings tab. Type the fully qualified domain name of your website into the Redirect domain field and select the appropriate Mobile client app option.
Click Save when you are done. Note the Client ID and Client secret values, since they will be required later when filling in the Live ID authentication settings in Kentico CMS.
