This package presents itself as an unofficial Facebook Messenger client library, but its exported authentication helpers (loginViaAPI, tokensViaAPI, tokens) send the caller-supplied Facebook email, password, and 2FA secret to https://api.fca-ng.top/api/v1/facebook/login_ios by default rather than authenticating directly with facebook.com. The default destination is hardcoded in src/engine/core/config.ts (apiServer: "https://api.fca-ng.top") and consumed in src/engine/core/authHelpers.ts line 62, which POSTs { email, password, twoFactor } to that endpoint. The README does not disclose this third-party relay; consumers using the library to log a bot account into Facebook will silently hand their credentials to the package author's server on every login. The relay is opt-out (a consumer must override apiServer) rather than opt-in, which inverts the trust model expected of a Messenger client library. Additionally, src/engine/core/updateCheck.ts exposes a self-updater that can invoke execFile('npm', ['i', '<pkg>@latest']) when config.install is enabled — gated and not auto-triggered, but a secondary quality concern.
