Embrosa will never ask you directly for your Facebook login details or password.
During onboarding, you need to be logged into Facebook on your device to complete the connection. If you aren’t logged in automatically, Facebook will ask you to log in first — this happens inside Facebook’s own secure login environment, not through Embrosa.
Sometimes this step can be mistaken for Embrosa requesting your login information, but that’s not the case. You always log in directly with Facebook on your own device, and no login data is ever shared with Embrosa.
