forgot my macbook air login password
six month ago I bought a new macbook air. i choose a password and used as well the finger print identification by the power button. I did not write down the password, so, i forgot it. after a while i turned it off. when i turned on, the finger print on the power button was not enough, it asked me for password as well. I tried all the passwords i usually use.it did not work.
please I need to be able to use my new macbook. thank you.
