What should I do if I find a login from an unfamiliar location? – ATPBot

If you see a location that you don't recognize, first check if it's related to your mobile device. Often, when signing in through a mobile device, you're routed through an IP address that doesn’t actually reflect your actual location.

If you don't recognize a location and it's not connected to a mobile device, it could be because:

We have inaccurate information: Sometimes we can only provide an approximate location that may appear inaccurate compared to your actual location.
You forgot to log off: You might be seeing the location of a mobile device you're still logged in to. If you think you've left yourself logged in on someone else’s mobile device, you can log yourself out.
Someone else has access to your Facebook account: If you think someone else is logged in to your account, you should first log yourself out and then secure your account by changing your password.
