Where: Settings › Develop, the Id prefix field.
Key: developIdPrefix. Type: text. Default: com. followed by your account name.
Every extension has a globally unique id like com.yourname.word-count. Make an extension and switchboard ext new build it from this prefix and the extension's name. A word with no dot ("kyle") becomes com.kyle. Changing it affects extensions you make from then on; extensions you already made keep their ids.
