When changing your password, it is highly recommended
that you change this password to something you can remember and
no one else can easily guess. It should not be a word in any English
or foreign dictionary (on-line dictionaries can be used in password
breaking programs) nor a proper name. It should contain a couple
of digits or capital letters (UNIX is case sensitive so it distinguishes
between upper and lower case), and should be 8 characters in length.
Use the passwd command to change your password. It will
ask you your old password, and then prompt you for your new password.
You will be asked to retype the new password to ensure that there
were no spelling errors. None of these passwords will be echoed
on the screen. If you change your password on the machine named
math, it will automatically be changed on all the machines
in the Math Department. For example:
math joe % passwd
Changing password for joe on math
Old passwd:
New passwd:
Retype new passwd:
math joe %
You should not give anyone your password. If anyone else needs the
use of an account, they must get their own.
