Facebook active sessions?

[Edward]

I have the password to my girlfriends facebook account. My question is, is there a way I can log into her account anonymously so it doesn't show up on her active sessions list?

If there is not a way, does it only show up the first time I log in, or every time I log in? For example:
I log into her account 10am. It logs on her active session I logged in.
I log out
I log back in at 4pm.
Does it show me again logging in at 4pm, or just the once at 10am?

Yes it shows logging in again.
