In order for your website to be able to synchronize content with Agility CMS (using the .NET Sync Model), use the Agility.Web .NET REST API, or generate a CMS preview key, you'll need to know what your instance's Security Key is.
You can retrieve the Security Key by following these steps:
- Login to the Agility Content Manager
- Navigate to Settings > Content Manager > Global Security
- Copy the value of the Security Key
