PASSWORD RIDDLE

A brother wanted  to use his brother's desktop
computer. When he opens it, he finds out that it was  password protected. Now, he clicked  on the hint and the following appears in front of him:
1 Jug
 2 Birthdays
3 Fights
4 Cars
2 Laptops
1 Watch

He was left confused entirely. He had no clue.
Can you help him with the password?
