Can I see if someone has logged onto my facebook account?

[R]

I am thinking that my roommate might be logging onto my facebook
account using the computer that we share. Is there anyway to see
what times that the facebook account has been logged into?

Go to your account settings> Security> then click "Active Sessions"

What does Active Sessions mean?

The Active Sessions section of your Security Settings page shows you a list of the recent times your Facebook account has been accessed. Each entry includes the date, time and approximate location when signing in, and the type of device used to access your account. You will also see the option to end any active session on the right side of each entry.

If you're on a computer, find your security settings.

Note: The location you see is based off of the IP address used to access your account. If you want to know the specific IP information of a login, simply hover your mouse over that session’s location data.

What does it mean if I don’t recognize a location in my Active Sessions?

If you see a location that you don't recognize, first check to be sure that this session isn't connected to your mobile device. Often, when signing in through a mobile device, you are routed through an IP address that doesn’t actually reflect your physical location.

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

We have inaccurate information: We can only provide an approximate location so our information will be wrong sometimes.

You forgot to log off from another location: If you think you've left yourself logged in on someone else’s device, simply click the end activity link to the right of that session information to log yourself out.

Someone else has access to your Facebook account: If you think someone else is logged in to your account, end the suspicious session by clicking End Activity (or Remove on mobile) at the right of the session information. After you end the session, secure your Facebook account by changing your password. We also recommend changing your email password, as anyone with access to your email can gain access to your Facebook account.
