Task: Set or Change User Password 

Type passwd command as follows to change your own password: 
$ passwd 
Output: 

Changing password for vivek 
(current) UNIX password: 
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully 

The user is first prompted for his/her old password, if one is present. This password is then encrypted and compared against the stored password. The user has only one chance to enter the correct password. The super user is permitted to bypass this step so that forgotten passwords may be changed. 

A new password is tested for complexity. As a general guideline, passwords should consist of 6 to 8 characters including one or more from each of following sets: 

    Lower case alphabetics 
    Upper case alphabetics 
    Digits 0 thru 9 
    Punctuation marks
