I never used FB, to much 'big brother' for me :-)
BTW Your password created 5 keys for you.
By default you probably logged in with the "master" key.
Not a good idea as it enables access to your $$$.
It's better to log in with your Private POSTING key.
go to Profile >Wallet > Permissions and copy paste all FIVE keys to a safe place
then log out & log back in with POSTING key.
