 Here is some information about API keys and client secrets:
+- You must keep these values secure. For details, see [Security of API Key and Client Secret]
 - One UID2 participant can have multiple keys.
 - Each key has a set of [permissions](gs-permissions.md) that determine the endpoints you can use it on.
 - Each key has a corresponding client secret.
