Before you connect a real account you want to know what happens to the keys. This is that answer, in the detail a security or platform review asks for.

How she connects

Where credentials live

The two are not stored the same way, and the difference matters for a review.Anything you type in is encrypted with AES-256 before it reaches the database: the credentials above, the Skool session cookie, your organization’s API key, and the client secrets of any OAuth app you register.Tokens the platform issues through an OAuth flow are stored as the platform returned them. For those the database is the security boundary, so encrypt the volume and keep access to it narrow.

What that means for you

On the cloud

The token is issued by the platform through its own screen, carrying only the scopes you approved

Self-hosting

Tokens and post content live where you put them, and the boundary above is yours to act on

Building on top

The API and MCP use the same authenticated flows and the same platform limits
Storage settings and ENCRYPTION_KEY: Configuration reference. Setting up your own provider credentials: OAuth configuration.
