By default, the embedded Deployment Manager package feed does not require an API Key. If you want to control who can push packages to the feed, you can add an API key:

1. On the computer where you installed the Deployment Manager server, go to the installation location. By default, this is:
   C:\Program Files (x86)\Red Gate\Deployment Manager
2. Open the NuGet folder, and then open the web.config file in a text editor.
3. Under <appSettings>, change the key="requireApiKey" value to "true".
4. For key="apiKey", specify the value you want to use as the API key (password) for the feed.
5. Save your changes to web.config.

The API key you specified will now be required when any user wants to push packages to the Deployment Manager feed.
