YOUR NEXT STEP
Review or remove an app’s Facebook access
Start here
Review the connection in Facebook’s Apps and Websites settings. This covers access previously granted to an outside service. An app appearing here does not by itself mean your account was hacked. If you entered your Facebook password into a suspicious service or see unfamiliar account changes, also follow the compromised-account guide; removing one connection is not a complete security check.
This helps you choose a next step. Look for the reason for a restriction in the Instagram or Facebook notice.
