From the Facebook documentation https://developers.facebook.com/docs/facebook-login/guides/access-tokens#apptokens:
> Note that because this request uses your app secret, it must never be made in client-side code or in an app binary that could be decompiled. It is important that your app secret is never shared with anyone. Therefore, this API call should only be made using server-side code.
## Impact
This token can be used to modify Facebook App settings.
