On computer systems where multiple users share disk
space and system resources, each user is given a
computer account.
How does the system know who is authorized to access
and use this account?
The user enters a password. If the user enters the
correct password, access is granted.
When you first get your account, some computer
systems assign a password to you and you can't
change it, but on the vast majority of systems, including
the UNIX workstations in, it is up to the user to select a
password for his or her account.

important thing you can do to protect your information

instances it may constitute a security breach as
