The threat to personal information privacy has never been greater than in this technological age. The use of computers to collect and store information has allowed more people and companies to serve as information facilities. It is now easier and less expensive to transfer data from one place to another. Information about a person's buying habits and credit history are now easily available over the Internet. This technological revolution means that more people have access to your personal information by both legal and illegal means.
Passwords are only a partial protection against loss of privacy.
If you give someone else your password, or leave it lying around, other people could obtain access to your information. This is true of computers, ATMs, and online bank accounts. As technology advances, hackers become more and more prevalent. Some hack maliciously. Some do it just because they can.
