beside of typing in password, there are others way to log in.
1, answer a math question. it is good for those study who facing public exam.
2, spell an english word, which the study dun know.
generally, a question related to one's study or business.
but those are not for security. ( well, if a very difficult math question. i think no hacker can do it :P good for using in lab)
for security, one can try "a question bank". everytime, PC will ask you a queation about your business, your personal stuff. let say, "what is the log out time last time?"
