I've recently turned on the setting to be notified when an unrecognised device logs into my Facebook account.
However, I think that someone has used my account on another device BEFORE I turned this on. If they attempt to login again, will I be notified or will their device be classed as a recognised device?
You can find all Extended Permission Here publish_stream will be required if the site want to post something on your wall, otherwise will throw an error with message
(#200) The user hasn't authorized the application to perform this action
Have you tried going to Account Settings -> Security -> Active Sessions?
The Active Sessions page shows a list of sessions that are currently open - whether they be other browsers on the same computer or different locations. You have the option to end any of the active sessions at any time.
To see the IP address used to calculate the location, just hover over the location. For example, in the Location field, it might say: Philadelphia, PA. Just hover your mouse over it, and it will say Location estimated based on IP = 12.345.67.89.01 (example IP address used).
(excuse the white boxes, those represent sensitive locational data).

If they've logged in successfully before from that device, there's a good chance it will be classified as a recognized device.
However, you can see which devices your Facebook account is currently logged into, and you can log yourself out of any of those devices. From the dropdown menu at the top of the Facebook site, go to:
If you see any unrecognized devices there, or devices that you know aren't yours, log yourself out by clicking the three dots to the right, then Log Out.
Logging out of all current sessions, combined with changing your Facebook password, will require anyone logging into your account from another device to know your new password in order to log in as you again.
