Facebook App Keys

Description

General

• Documentation: https://developers.facebook.com/docs/facebook-login/access-tokens/#apptokens
• Summary: Facebook access tokens are strings used for identification and are of three types: either to identify a user, an application, or Page. Application access tokens are used to modify and read app settings. They can also be used to publish Open Graph actions. They are generated using a pre-agreed secret between the app and Facebook and is then used during calls that change app-wide settings.
• IPs allowlist: This feature is not available.
• Scopes: App access tokens are only limited to access and modify application data (no reach on users, pages, or clients).

Revoke the secret

There is no direct information on how to revoke app access token.
