My MacBook Air account is locked

I tried to use my macbook with my track id, but i was told i need to enter the password to enable the track id.

So I did. But it said the password was wrong, so i tried it again (i even checked capitalised letters). I NEVER forget my passwords since all the passwords of my accounts are same.

But it still said its wrong.. So i was keep trying and my account have been locked for half an hour to an hour, to three hours, and now, 8 bloody hours...

Please help me ive got lots of courseworks to do..
