Why am i getting this notification?

[BILL]

I deactivated my Facebook account and I keep getting notifications that say "Facebook username and password incorrect." Is someone trying to get into my account? Or activating it? No one will ever guess my password. I just want to know if someone is trying to get into my account

No one can get ur account that was deactivated yet he or she can open up plenty of facebook accounts a day. Those notifications are just reminding u for reactivate it any time u feel u want
