You may find that you want to protect your auto update files on your web server with a username or password. The framework allows you to set a username and password on a per build profile basis. The framework currently supports basic and digest authentication.
If you haven't already, specify the base auto update url in the General tab. For more information see this lesson.
You can customize settings for individual builds on the Build Profile. From the Build Profile tab select the build profile you want to set the username and password for.
Enter the username and password that your server requires to access files in the directory where your auto update files will be located. When your application checks for updates the username and password will be used to authenticate with the server.
