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.
