          You have $12$ choices for the first character.



          You then have $11$ choices for the second character (anything except whatever you chose for the first character).



          Similarly, $11$ choices for the third character (anything except whatever you chose for the second character).



          And also $11$ choices for the fourth, fifth and sixth character.



          Hence, there is a total of $$12 times 11 times 11 times 11 times 11 times 11 = 1932612$$ possible passwords.
